    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?

    But people need a map to find it. And in 1882 when surveyors set out to map a part of Minnesota, they got confused and somehow mapped a great swath of ancient trees as a lake. For more than seventy-five years, the mistake stayed on the map, and the forest remained safe from logging—no lumber baron expects to find timber in a lake, after all. The Lost Forest tells the story of this lucky error and of the 144 acres of old-growth red and white pine it preserved. With gentle humor, Phyllis Root introduces readers to the men at their daunting task, trekking across Minnesota, measuring and marking the vast land into townships and sections and quarters. She takes us deep into a stand of virgin pine, one of the last and largest in the state, where U.S. history and natural history meet. With the help of Betsy Bowen’s finely observed and beautiful illustrations, she shows us all the life that can be found in the Lost Forest.Accompanying the story is a wealth of information about the Cadastral Survey and about the plants and animals that inhabit forests—making the book a valuable guide for readers who might want to look even deeper into the history of Minnesota, the flora and fauna of old-growth forests, and the apportioning of land in America.
