The Secret Zoo is a series of children's novels by American author Bryan Chick.
Four kids: Noah Nowicki, his sister Megan, and their friends Richie and Ella live across the street from the zoo.
Here they find that there is a magical secret society that they become a part of where humans and animals can live together equally.
A reviewer from TheReadingTub praised book 1 of the series, calling it "a nice choice for reading aloud with a younger crowd".
Kirkus, in a review of Secrets and Shadows, said that "while the tension between the preteen protagonists and the teens is both tangible and interesting, this installment feels more like novel-length worldbuilding than a story in itself.
