Meg Pepper has a fulfilling career and a happy family. Most days she's able to keep it all together and glide through life. But then, in one unalterable moment, everything changes.

After school pickup one day, she stops her car to wave a teenage boy across the street...just as another car comes hurtling down the road and slams into him.

Meg can't help but blame herself for her role in this horrific disaster. Full of remorse, she throws herself into helping the boy's family as he rehabs from his injuries. But the more Meg tries to absolve herself, the more she alienates her own family--and the more she finds herself being drawn to the boy's father.

Soon Meg's picture-perfect life is unravelling before her eyes. As the painful secrets she's been burying bubble dangerously close to the surface, she will have to decide: Can she forgive herself, or will she risk losing everything she holds dear to her heart?
