The Last Zookeeper (2025 Carnegie Medal for Illustration Nominated)

A master of the wordless form imagines a futuristic Noah’s Ark in a luminous sci-fi parable for our changing world.

The Earth has flooded. The only signs of humankind are the waterlogged structures they left behind. Peeking out from the deluge are the remnants of a zoo, home to rare and endangered animals, survivors of long neglect. Tender-hearted NOA is a construction robot who's found new purpose as the caretaker of the zoo’s beleaguered inhabitants. Bracing for the next storm, NOA builds an ark from the wreckage in search of new land, only to discover something even more profound. With boundless compassion and sweeping scenes of sea and sky punctuated by detailed wordless panels to pore over, Caldecott Honor–winning creator Aaron Becker delivers a timely and concrete message about the rewards of caring in even the most difficult of times that is sure to inspire the dreamers among us.

Aaron Becker is the best-selling author of the award-winning Journey trilogy and other books for children young and old, including The Tree and the River and A Stone for Sascha. When he’s not home with his wife and two daughters, he can be found creating something new in his backyard studio in western Massachusetts.
