New York City in the 1860s was a mess: crowded, disgusting, filled with garbage. You see, way back in 1860, there were no subways, just cobblestone streets. That is, until Alfred Ely Beach had the idea for a fan-powered train that would travel underground. On February 26, 1870, after fifty-eight days of drilling and painting and plastering, Beach unveiled his masterpiece—and throngs of visitors took turns swooshing down the track. The Secret Subway will wow readers, just as Beach’s underground train wowed riders over a century ago.

If you lived in a village in South Africa, the outside of your house might tell the story of your family. And if you lived in a floating green house in the Netherlands, you could rotate your house to watch both the sunrise and sunset.

Showing the tremendous variety of dwellings worldwide—log cabins, houses on stilts, cave dwellings, boathouses, and yurts—this book addresses why each house is built the way it is.

    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?
