Imaginary Friend

by Stephen Chbosky

Single mother Kate Reese and her son, Christopher, flee an abusive relationship in the middle of the night. Together, they find themselves drawn to the tight-knit community of Mill Grove, Pennsylvania.

Initially, Mill Grove seems like the perfect place to settle down. Then Christopher vanishes for six days, until he emerges from the woods at the edge of town, unharmed but not unchanged. He returns with a voice in his head only he can hear and a resolve to build a treehouse in the woods by Christmas...
