Hot for the Soldier by Elisa Leigh

Marcus Romero is a soldier. One of the first things Marcus learned when he joined the Army was that soldiers never leave a man behind. Except she isn’t a man, she’s Hadley, the sexy waitress he’s been eyeing since he got home from his last tour. Now she’s in trouble and he’s the only one who can save her.
Hadley Taylor is just trying to make ends meet by working at the local bar in town. Eventually, she gets unwanted attention from a very dangerous man. Hadley does what she has to do, until even that’s asking too much. On the run, she doesn’t know where to turn or who to trust. The only thing that matters is keeping her daughter safe.
