    She didn't know that young women had to go to work, that they traded an education for long hours of labor, that she was expected to grow up fast. But that did not stop Clara. She went to night school, spent hours studying English, and helped support her family by sewing in a factory. Clara never quit. And she never accepted that girls should be treated poorly and paid little. So Clara fought back. Fed up with the mistreatment of her fellow laborers, Clara led the largest walkout of women workers in the country's history. Clara had learned a lot from her short time in America. She learned that everyone deserved a fair chance. That you had to stand together and fight for what you wanted. And, most importantly, that you could do anything you put your mind to.“In her simple but powerful text Markel shows how multiple arrests, serious physical attacks, and endless misogyny failed to deter this remarkable woman as she set off on her lifelong path as a union activist.” --The Horn Book

    It is the love and cooking talent that Korean mothers and grandmothers mix into their handmade foods. For Chef Roy Choi, food means love. It also means culture, not only of Korea where he was born, but the many cultures that make up the streets of Los Angeles, where he was raised. So remixing food from the streets, just like good music—and serving it up from a truck—is true to L.A. food culture. People smiled and talked as they waited in line. Won't you join him as he makes good food smiles?

    But before she can work off her debt, an unthinkable chain of events unfolds: a capture by slave traders; weeks in a dark and airless hold; a landing in Cuba, where she and three other children are sold and taken aboard the Amistad; a mutiny aboard ship; a trial in New Haven that eventually goes all the way to the Supreme Court and is argued in the Africans’ favor by John Quincy Adams. Narrated in a remarkable first-person voice, this fictionalized book of memories of a real-life figure retells history through the eyes of a child — from seeing mirrors for the first time and struggling with laughably complicated clothing to longing for family and a home she never forgets. Lush, full-color illustrations by Robert Byrd, plus archival photographs and documents, bring an extraordinary journey to life.
