Both of them want a relationship—but is beginning it a big mistake?

On the outside, twenty-seven-year-old Darcy Larsen is a pretty, put-together professional--but inside she's falling apart. Eighteen months ago, she lost her fiancé in an accident she still blames herself for. After a successful transplant, her kidney disease seems to be in check, but she worries that her future children--if she has any--will also suffer from the same condition. And she's overcome with indecision about finding her birth mother, discovering potentially devastating information, and hurting her adoptive parents.

Mechanic Carter Donovan seems to have everything going for him at first glance. Stunning good looks. A wicked sense of humor. And a heart of gold. But Carter's seemingly perfect exterior hides a host of secrets. After a rough breakup and mounting medical bills from a medical emergency that left him drowning in debt, he doesn't feel like the catch everyone says he is. Plus, he's about to turn thirty--with no romantic prospects on the horizon.

When Darcy's Lexus breaks down in her doctor's parking lot, Carter appears on the scene to try to jump start her car--and her heart. But despite their immediate connection right from the start, the two have perhaps too many obstacles to overcome. Carter questions if getting involved with Darcy will be his next big mistake. And Darcy wonders if she can ever move past her grief and guilt to embrace the gift of Happily Ever After that's dangling in front of her.
