Julia Gilliland has always been interested in the natural world around her. She particularly enjoys studying the fossils and formations in the magnificent cave near her father's house. The cave seems plenty safe—until the day a mysterious intruder steals the rope she uses to climb out. Rafe Kincaid is a man used to being in control—of himself, his brothers, and his family's ranch. The last thing he expects is to find a woman trapped in the cavern on his land—or to be forced to kiss her! Rafe is more intrigued by Julia than any woman he's ever known. But when their developing relationship threatens a reconciliation with his brothers, will Rafe have to choose between his family and this new love that could heal his troubled heart and secure his happiness?

He casually agrees to a marriage of convenience... never expecting to fall in love with his bride. Ethan Kincaid proposes marriage with the same detachment he gives every decision. Audra Gilliland accepts his proposal so she can stop being a burden to her newly married stepdaughter. But Ethan never expected Audra to affect him so profoundly, and it terrifies him. Someone he loved was once seriously injured on his watch, and he won't let that happen again. If Audra will just do as he says, he can keep her safe from the dangers that lurk on the ranch. Audra has been cared for all her life by one man or another—and they've done a poor job of it. Now she's planning to stand up for herself. And her new husband had better agree or get out of her way! Can two fearful hearts—wary of getting in too deep—become two trusting hearts, willing to let go and fall in love?

Seth Kincaid survived a fire in a cave, but he's never been the same. He was always a reckless youth, but now he's gone over the edge. He ran off to the Civil War and came back crazier than ever. After the war, nearly dead from his injuries, it appears Seth got married. Oh, he's got a lot of excuses, but his wife isn't happy to find out Seth doesn't remember her. Callie has searched, prayed, and worried. Now she's come to the Kincaid family's ranch in Colorado to find her lost husband. Callie isn't a long-suffering woman. Once she knows her husband is alive, she wants to kill him. She's not even close to forgiving him for abandoning her. Then more trouble shows up in the form of a secret Seth's pa kept for years. The Kincaid brothers might lose their ranch if they can't sort things out. It's enough to drive a man insane—but somehow it's all making Seth see things more clearly. And now that he knows what he wants, no one better stand in his way.
