The Cop's Missing Child (Harlequin Romantic Suspense Series #1719)

Small-town cop Mac Riordan lost his wife in a car crash, but his infant son survived, only to later be kidnapped. Now, five years later, Mac locates him living in Anniversary, Texas, with beautiful Emily Gilley. The more he gets to know this mysterious mother of his son, the less he's convinced she's a coldhearted kidnapper. She might be a victim just as much as he is. So when Emily's under-the-radar lifestyle is suddenly discovered, Mac comes clean. The threats against her—against their child—escalate and Mac must risk it all to protect his son…and the woman who's brought him back to life.
