It's been eighteen months since Darcy Larsen's fiancé, Jace, was killed in a car accident on his way to pick up Darcy's medicine from the pharmacy. Eighteen months of missing him and struggling to overcome her heartache, grief, and guilt. Unwilling to open up her heart to more hurt, Darcy is sure her one chance at a Happily Ever After is gone, until a random encounter with a handsome stranger changes everything. Carter Donovan has a new lease on life. An emergency kidney transplant saved his life, but while he's eternally thankful to the anonymous donor, he can't help but feel like a burden to his family. Forced to move in with his sister and her family, he's ready to move forward--past his broken engagement and his former illness and embrace his second chance at life and love. When Darcy's car breaks down and Carter rushes to the rescue, these two souls are thrown together in an unexpected way. As they start to date, Darcy feels herself coming back to life, and Carter begins to believe in the future again. But as they grow closer and open up more about their hopes, fears, and pasts, an explosive secret threatens to break down the gentle romance they've built. Carter's transplant isn't as anonymous as he'd first thought, and its connection to Darcy--and her fiancé Jace--could shatter everything they've built.
