Here's the blurb:
Like most children, ten-year old Jimmy wonders where the Tooth Fairy keeps all those teeth. It's a silly question to laugh about. He plays along to get some coins, confident there's no such person. As he and his friends know, their mothers play the role of the Tooth Fairy, but in the middle of the night, Jimmy's world turns upside down. He learns there's more to his mother than he ever imagined, and the Tooth Fairy isn't so harmless.
Thanks to Lyn Perry and Stuart West for their comments on the manuscript and K. M. Carroll for that awesome cover.
