Warrior’s Heart by Bianca D’Arc

He’s home to claim the girl he never forgot…but more than war memories have changed him.

Hal’s best-friend status with Casey’s brother always meant that the one woman he wants is strictly off limits. But now that he’s back from a harrowing mission in the ancient Iraqi city of Babylon, all bets are off. The strangely mystical experience left him and his Special Forces team with a new appreciation for life—and strange new abilities they are only beginning to understand.
Casey never thought she’d have a shot with the strong, silent Green Beret. Something about him has changed, though, and old feelings have risen up, demanding an answer. And her answer is an unequivocal yes. Now, to break the news to her brother and hope it doesn’t come to blows.

Her brother’s reaction becomes the least of her worries when Hal singlehandedly stops a car from running her down, then falls into her arms, weak from some kind of strange reaction. Whatever went down in Iraq has changed Hal and made him a target of foreign agents who’ve found his one vulnerability…Casey.
