My Heart's Treasure

Ladies' man Anton Romero is smitten with Vivian Wentworth from the very beginning. He wants nothing more than to get to know the stiff Miss Wentworth—and perhaps make her relax so she’s not so uptight—until he learns she's investigating him for a crime he didn't commit.
Innocent and naïve, Vivian is convinced that Anton is the outlaw her superiors have painted him. But her over-zealous determination puts both of them in danger and he is forced to play the honorable rogue.

Sweeping her away to Padre Island off the coast of Spain seemed like a clever idea at the time. But how can he protect them both from his uncle's murderous games when Anton's heart falls victim to a woman as full of independence as she is desire.
