The unexpected hero

the long version

Nurse practitioner Kristin Tate had hoped her new job would be a welcome change from her military tragedy--not a chance for Dr. David Marcus to set her vulnerable heart on fire. But there was more to the handsome doctor than his rough, war-hardened exterior suggested, and soon Krissie wondered if she had finally found the love she desperately craved....Until patients started dying and she became a suspect for murder.David knew the beautiful nurse wasn't a killer, and powerful feelings for her threatened his best-laid plans. With evidence mounting, could he help clear Krissie's name before she turned up on someone's fatal list?
