Trapped with the Covert Ops Soldier

This book was previously published under the title Playing Doctor. It has been extensively revised and lengthened.
Dr. Abigail Westward is home after military duty in Asia and the Middle East. She's taken up an unusual hobby: tossing lit dynamite sticks into the waters of Lost Lake, Montana. Spencer "Smitty" Smith, a fellow soldier and friend may be the only man who might be able to find out why Abby has taken up her new explosive pastime.
Smitty loves Abby, has from damn near the moment he met her. He's stayed at arm's length because getting involved with anyone while on a combat mission is just plain stupid. But combat is over and he's waited long enough.
Smitty's been hired by the town of Bandit Creek to ride herd on her, and Abby is resistant to the idea until someone attempts to shoot her in the middle of town. Now she and Smitty have to figure out who wants to kill her and why before he'll go. He must go. He's her only weakness and the one man who knows her terrible secret.
She's a doctor who's guilty of murder.
