When ten-year-old Felix drops a penny in the wishing fountain at the center of town, he really doesn't expect his sixteen-year-old sister to suddenly like him again, or to offer to share a cinnamon bun or watch cartoons like they used to. She hasn't even remembered she was supposed to give him a ride home! But someone else is at the fountain too: a strange old man with a fishing pole who claims to be invisible. To Felix's amazement, he learns that the old man is a Wishkeeper, and he needs an apprentice! But being a Wishkeeper's apprentice isn't just about organizing incoming wishes and untangling wish snags: a strange wolf-man who's been haunting Felix's dreams is real and a threat to every wish that has ever been granted in the town of Whittlestone, the town's Wishkeeper, and Felix himself. With lively illustrations, this sweet adventure bubbles with charm and heart.
