Beneath His Armor

He built walls to protect himself. She's ready to break through them-one kiss at a time. Callum is a billionaire rancher, heir to one of Texas's most powerful dynasties. Rugged, reserved, and fiercely private, he's a man used to control. Love? It's not part of the plan. He doesn't believe in it-and never will. What he does want is an heir. No strings. No messy emotions. Enter Mackenzie-smart, fiery, and running from a dangerous past.
When fate throws her into Callum's path, she's not looking for love either. She needs protection, and the intimidating cowboy with ice-blue eyes might be her only shot at safety. But neither of them expects the slow burn of desire to ignite into something neither can deny. Now, Mackenzie is determined to show Callum that behind his armor beats a heart worth fighting for. But will her love be enough to melt the man who's sworn never to fall?
