A fast-paced and exciting read for middle grade fantasy, mystery, and animal buffs. Something strange is happening at the Clarksville City Zoo. Late at night, monkeys are scaling the walls and searching the neighborhood—but what are they looking for? Noah, his sister Megan, and their best friends, Richie and Ella, live next door to the zoo. Megan is the first to notice the puzzling behavior of some of the animals. One day Megan disappears, and her brother and their friends realize it's up to them to find her. Their only choice is to follow a series of clues and sneak into the zoo. But once inside, they discover there's much more to the Clarksville City Zoo than they could ever have guessed... The author originally had the idea for The Secret Zoo when he was nine and wondered what would happen if zoo exhibits had secret doors that allowed kids to go inside—and the animals to come outside. He brings that sense of adventure and excitement to this story, making it a favorite for home and classroom reading along with such middle grade fantasy favorites as The One and Only Ivan.

"We will need you as Crossers, and we will need you not only to be brave—but to be fearless." Mr. Darby paused, giving the scouts time to digest his words. Then he continued. "I want you to think before answering. Can you accept this challenge?" Only weeks after their return from the Secret Zoo, Noah and his friends must go back—and face their biggest challenge yet. With monstrous sasquatches freely attacking the denizens of the zoo and the evil Shadowist at large, the fate of the world is at stake.
