The mending summer

"For Georgia, this summer is shaping up to be a big disappointment. Mama is busy studying for her biology degree. Daddy is working nights, and often the man who comes home isn't Daddy. He's a man who looks like Daddy, but walks a little wobbly. Who sounds like Daddy, but sings a little too loud. Georgia calls him the Shadow Man. So now, instead of riding horses with her friends at camp, Georgia is sent off to the country to stay with her mysterious great-aunt for the summer to avoid her parents' fighting. There, a lonely Georgia meets a mysterious friend named Angela and together, they discover a magical lake--one that can make wishes come true. At first, the lake offers Georgia a thrilling escape from her worries and hope that she can use its magic to heal her family. But as things grow worse at home, a troubled boy appears at the lake and the wishes threaten to spiral out of control..."--From the publisher's web site.
