Hike the American desert in the fourth book in the Nature Discovery Book series. Charley Harper's What's in the Desert? explores a surprising abundance and variety of flora and fauna. Zoe Burke's rhyming text introduces young readers to thirty-five different denizens of the desert – from the Gila Monster to the Gila Woodpecker, the Cactus Wren to Cactus flowers. All are depicted with colorful images taken from Harper's painting The Desert, originally featured on a poster commissioned by the US National Park Service.
