Colleen AF (Ann Felicity) Venable is the author of many books for kids and was longlisted for a National Book Award for her YA graphic novel debut, Kiss Number 8. Colleen splits her time between Brooklyn, New York, and an old house in Western Massachusetts that she’s rebuilding with friends. When she’s not writing books, she can be found working at animal rescues, failing at imitating birdcalls, and getting very excited when she spots a frog.
