Switchback (Harlequin Intrigue)

A KIDNAPPED CHILD. A DEADLY ENEMY. Bud Mac Phearson's job is to protect Mallory Christiani and her young daughter, Emily—not to get personally involved with either. But after Emily disappears and the trail leads directly to a well-known crime boss, Mac can't refuse the beautiful single mother's pleas for help. With assassins hot on their trail and danger around every corner, the tentative partners race to find the missing key needed for the ransom…even as they try to fight the attraction blooming between them. But when Mac trades his own life for Emily's, Mallory must risk it all to save the man she's come to love…
