    While growing up in housing projects in Puerto Rico and Miami Beach, Jaquira Díaz found herself caught between extremes: as her family split apart and her mother battled schizophrenia, she was surrounded by the love of her friends; as she longed for a family and home, she found instead a life upended by violence. From her own struggles with depression and sexual assault to Puerto Rico’s history of colonialism, every page of Ordinary Girls vibrates with music and lyricism. Díaz triumphantly maps a way out of despair toward love and hope to become her version of the girl she always wanted to be.With a story reminiscent of Tara Westover’s Educated, Roxane Gay’s Hunger, and Terese Marie Mailhot’s Heart Berries, Jaquira Díaz delivers a memoir that reads as electrically as a novel.

    Her strict mother worked hard at cultivating her own role as the long-suffering ex-wife of bad-boy poet Lord Byron while raising Ada in isolation. Tutored by the brightest minds, Ada developed a hunger for mental puzzles, mathematical conundrums, and scientific discovery that kept pace with the breathtaking advances of the industrial and social revolutions taking place in Europe. At seventeen, Ada met eccentric inventor Charles Babbage, a kindred spirit. Their ensuing collaborations resulted in ideas and concepts that presaged computer programming by almost two hundred years, and Ada Lovelace is now recognized as a pioneer and prophet of the information age. Award-winning author Emily Arnold McCully opens the window on a peculiar and singular intellect, shaped -- and hampered -- by history, social norms, and family dysfunction. The result is a portrait that is at once remarkable and fascinating, tragic and triumphant.

    At first things went smoothly for the Clinton 12, but then outside agitators interfered, pitting the townspeople against one another. Uneasiness turned into anger, and even the Clinton Twelve themselves wondered if the easier thing to do would be to go back to their old school. Jo Ann--clear-eyed, practical, tolerant, and popular among both black and white students---found herself called on as the spokesperson of the group. But what about just being a regular teen?

    In coming to terms with her decision to publicly out her mother, Gail changed how she looks at race and heritage.

    A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with nature’s most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.At the end of the seventeenth century—an age of religious wars, plague, and the Great Fire of London—when most people saw the world as falling apart, these earliest scientists saw a world of perfect order. They declared that, chaotic as it looked, the universe was in fact as intricate and perfectly regulated as a clock. This was the tail end of Shakespeare’s century, when the natural land the supernatural still twined around each other. Disease was a punishment ordained by God, astronomy had not yet broken free from astrology, and the sky was filled with omens. It was a time when little was known and everything was new. These brilliant, ambitious, curious men believed in angels, alchemy, and the devil, and they also believed that the universe followed precise, mathematical laws—-a contradiction that tormented them and changed the course of history.The Clockwork Universe is the fascinating and compelling story of the bewildered geniuses of the Royal Society, the men who made the modern world.

    She was accepted and became the first American woman astronaut to fly in space! Among her other accomplishments, she played tennis like a professional, was an astrophysicist who helped develop a robotic arm for space shuttles, and later, through Sally Ride Science, worked to make science cool and accessible for girls. Sally Ride, who died on July 23, 2012, will continue to inspire young children.

    Twelve-year-old Cindy has just dipped a toe into seventh-grade drama—with its complicated friendships, bullies, and cute boys—when she earns an internship as a cub reporter at a local newspaper in the early 1970s. A (rare) young female reporter takes Cindy under her wing, and Cindy soon learns not only how to write a lede, but also how to respectfully question authority, how to assert herself in a world run by men, and—as the Watergate scandal unfolds—how brave reporting and writing can topple a corrupt world leader. Searching for her own scoops, Cindy doesn’t always get it right, on paper or in real life. But whether she’s writing features about ghost hunters, falling off her bicycle and into her first crush, or navigating shifting friendships, Cindy grows wiser and more confident through every awkward and hilarious mistake.

    Although best-known for her work A Raisin in the Sun, her short life was full of extraordinary experiences and achievements, and she had an unflinching commitment to social justice, which brought her under FBI surveillance when she was barely in her twenties. While her close friends and contemporaries, like James Baldwin and Nina Simone, have been rightly celebrated, her story has been diminished and relegated to one work—until now. In 2018, Hansberry will get the recognition she deserves with the PBS American Masters documentary "Lorraine Hansberry: Sighted Eyes/Feeling Heart" and Imani Perry's multi-dimensional, illuminating biography, Looking for Lorraine.After the success of A Raisin in the Sun, Hansberry used her prominence in myriad ways: challenging President Kennedy and his brother to take bolder stances on Civil Rights, supporting African anti-colonial leaders, and confronting the romantic racism of the Beat poets and Village hipsters. Though she married a man, she identified as lesbian and, risking censure and the prospect of being outed, joined one of the nation's first lesbian organizations. Hansberry associated with many activists, writers, and musicians, including Malcolm X, Langston Hughes, Duke Ellington, Paul Robeson, W.E.B. Du Bois, among others. Looking for Lorraine is a powerful insight into Hansberry's extraordinary life—a life that was tragically cut far too short.

    They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys’ club at NASA and on Capitol Hill. The USSR sent its first woman into space in 1963; the United States did not follow suit for another twenty years. For the first time, Martha Ackmann tells the story of the dramatic events surrounding these thirteen remarkable women, all crackerjack pilots and patriots who sometimes sacrificed jobs and marriages for a chance to participate in America’s space race against the Soviet Union. In addition to talking extensively to these women, Ackmann interviewed Chuck Yeager, John Glenn, Scott Carpenter, and others at NASA and in the White House with firsthand knowledge of the program, and includes here never-before-seen photographs of the Mercury 13 passing their Lovelace tests. Despite the crushing disappointment of watching their dreams being derailed, the Mercury 13 went on to extraordinary achievement in their lives: Jerrie Cobb, who began flying when she was so small she had to sit on pillows to see out of the cockpit, dedicated her life to flying solo missions to the Amazon rain forest; Wally Funk, who talked her way into the Lovelace trials, went on to become one of the first female FAA investigators; Janey Hart, mother of eight and, at age forty, the oldest astronaut candidate, had the political savvy to steer the women through congressional hearings and later helped found the National Organization for Women. A provocative tribute to these extraordinary women, The Mercury 13 is an unforgettable story of determination, resilience, and inextinguishable hope.From the Hardcover edition.

    How could she help these girls if she couldn't even be honest with herself and face her own demons? A fitful night led to pages and pages of scribbled notes with two clear words at the top: Me too.Tarana Burke is the founder and activist behind the largest social movement of the twentieth and twenty-first centuries, the me too movement, but first she had to find the strength to say me too herself. Unbound is the story of how she came to those two words, after a childhood growing up in the Bronx with a loving mother that took a terrible turn when she was sexual assaulted. She became withdrawn and her self split: there was the Tarana that was a good student, model kid, and eager to please young girl, and then there was the Tarana that she hid from everyone else, the one she believed to be bad. The one that would take all the love in her life away if she revealed.Tarana's debut memoir explores how to piece back together our fractured selves. How to not just bring the me too movement back to empathy, but how to empathize with our past selves, with out bad selves, and how to begin to love ourselves unabashedly. Healing starts with empowerment, and to Tarana empowerment starts with empathy. This is her story of finding that for herself, and then spreading it to an entire world.

    At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.

    The upper middle class splendor in which she and her siblings so happily lived was made possible by her mother's business in the Numbers, the informal lottery that powered African American communities across the United States. A poignant and revealing examination of how one family lifted itself out of poverty and into a completely different life, for good and bad, The World According to Fannie Davis introduces us to an unforgettable matriarch, and her daughter, whose ways of understanding still resonate today.Offering a daughter's perspective on her larger-than-life mother, Bridgett Davis traces her family's story as part of the Great Migration, showing how her mother and father arrived in Detroit from Tennessee carrying with them not just their own hopes but also those of their families. A child gifted with extraordinary powers of perception and understanding, Davis breaks the code of secrecy around her mother's business and in so doing reveals both her mothers' extraordinary sacrifices as well as her seemingly endless generosity. We come to understand just how keenly Fannie Davis believed in the power of money, and family, to make the world right.Moving, suspenseful and emotionally rewarding, The World According to Fannie Davis will change the way you understand the lengths a mother will go to provide for her family, and the way those sacrifices resonate over time, offering not just a moving portrait of one American family, but also a new way of understanding Detroit.
