James Henry used to be brave. He hasn't been the same since that fateful night at the lighthouse when his ma went searching for Dog. Now months later, he feels as small as the space between the numbers on a watch, nervous day and night, barely able to go outside. Even words have a hard time leaving his mouth. The only person he speaks to is Hattie, his courageous twin sister, who fiercely protects him, especially from bullies.

James Henry wants nothing more than to be brave again. However, finding his voice will mean confronting the truth about what happened at the lighthouse-a step James Henry isn't sure he can take. Until a blue moon is forecast, and as Gran has said, everything is possible under a rare blue moon . . .

* "An evocative, immediate novel with compelling characters and a wonderfully well-paced plot." --The Horn Book, starred review
