When Savannah knocks her abusive drunk stepfather out with a frying pan and takes her younger half-brother with her to flee, she has time to think back on her past and on her relationship with her mother. And interspersed between a story of running away and these reflections on her past, Savannah's mother Alice tells a story about her own teenage years, leading up to Savannah's birth.
This is a fascinating multi-layered story about family and choices, and how those choices change lives forever. At first, the parallel storyline really doesn't gel very well, but as the story continues, things come closer and closer together until an incredible oh shit moment at the end of the book. Truly memorable. Some rough moments in the story keep this from being a must-have classic, but it is still a great read.
