Mackenzie's Heroes (Mackenzie Family #3-3.5)
Navy SEAL Zane Mackenzie was a pro. No mission had ever gotten the better of him—until now. Saving the ambassador's gorgeous daughter, Barrie Lovejoy, had been textbook—except for their desperate night of passion. And though his job as a soldier had ended with her freedom, his duties as a husband had only just begun. For he would sooner die than let the enemy harm the mother of his child.
Talented trainer Maris Mackenzie was wanted for horse theft, but with no memory of that fateful day, she had little chance of proving her innocence or eluding the villains behind the prize stallion's disappearance. Her only hope for salvation? The stranger in her bed.
