When Therese Matheson's husband, Paul, was killed in Afghanistan, she thought she could hold what was left of their family together. But things have gotten so bad with her stepchildren that she's considering the unthinkable: giving up custody of Paul's kids. SGT Keegan Logan, a combat medic, knows a little about taking care of someone else's child. Three years ago, his live-in girlfriend gave birth to a daughter, Mariah, who was conceived while Keegan was deployed. Keegan ended the relationship, but when his ex abandons the baby and skips town, little Mariah has no one to care for her but Keegan. Keegan knows Mariah's real father: MAJ Paul Matheson. He doesn't know why Paul never manned up and took responsibility, but he's determined to find out. Only instead of finding Paul in Tallgrass, OK, he finds Therese. Therese is shocked by her attraction to Keegan - and that he seems to feel the same. But how will she react when Keegan reveals that her perfect marriage wasn't so perfect? Will Keegan and Mariah push her fragile family over the edge? Or with Keegan can she finally find a love worth holding onto?
