"Magical, exciting, and deeply moving. Lasky’s perfectly constructed fantasy is told in beautifully descriptive, soaring language, with invented words and names feeling just right and an abundance of detailed information about each animal’s habitat, attributes, and physiology." —Kirkus (starred review)
