Innocent Carina Ramirez was the last person Cody Callaway expected to see stealing into his steamy Mexican hotel room in the middle of the night. The beautiful, tenderhearted siren had risked her neck for Cody, and now there was only one thing for an honorable undercover cowboy to do! Carina had to warn Cody that someone was plotting his death. She couldn't turn her back, and when her protective older brother discovered them - together - he insisted they marry. But a marriage built on suspicion and force would never lead to true love...or could it?
