Bulletproof Heart

He's a bored billionaire. She's a destitute rancher. They have nothing in common. Unemployed and pregnant, April Cooper retreats to the family ranch where she's surrounded by disaster: her grandfather is dead, her uncle has disappeared, and someone's been shooting the cattle. April wants to raise her baby in peace and quiet, but she suspects the newly-arrived stranger offering to help is keeping secrets.
Wade Kelly Borne is searching for a corporate retreat location, but his conscience won't let him abandon a woman in need. Drawn to April's quiet strength, Wade sticks around to protect her and help discover who's terrorizing her ranch.  He should leave in a few days, but his heart has other ideas. He'd never fit into her lifestyle, and she wants no part of his, but they can't ignore their mutual attraction.
Are their differences irreconcilable, or is there hope for a future together?
