Rachel Berman wants everything to be perfect. An overprotective single mother of two, she is acutely aware of the statistical dangers lurking around every corner--which makes her snap decision to aid a stranded motorist wholly uncharacteristic. Len Bean is stuck on the shoulder with Olivia, his relentlessly curious, learning disabled ten-year-old daughter. To the chagrin of Rachel's children, who are about to be linked to the most-mocked girl in school, Rachel and Len begin dating. And when Len receives terrible news, little Olivia needs a hero more than ever.
But the world refuses to be predictable. When personal crisis profoundly alters Rachel's relationship with a wild, very special little girl, this perfectionist mother finds herself drawn into a mystery from her past and toward a new appreciation for her own children's imperfect lives.
