At fifteen, all Harper Whitman ever wanted (other than a best friend) was a mother--someone to care and nurture for her, someone to keep her warm, to love her. The last thing she expected was to find her mother...at the bottom of Hennepin Lake with concrete blocks chained to her legs. Suicide. From interviews and car rides, blooming friendships and crumbling lies, postcards and burnt love letters, mothers and their forgotten daughters, she's forced to ask herself: How well can we ever know somebody?
