A Texan for Hire (Harlequin American Romance Series #1540)

FIND YOUR SISTER 

Three words scrawled on a piece of paper just upended Abby Winchester's world. She'd never known she even had a sister. Abby's sure she'll learn the truth after traveling to the sleepy Texas town where she was born. And tall, brooding Clay Tanner may find the answers she needs, even if he does look more like a cowboy than a PI. 

The petite blonde who just hired him is tempting Clay to break his rule not to get involved with a client. But the former ATF agent isn't ready for a relationship—not after what once happened on his watch. Still, helping Abby uncover family secrets makes him wonder if it's time to put his own past to rest. Is Abby willing to face an uncertain future—together?
