Kansas City Crime Lab

He promised to keep her safe...without crossing any of his self-imposed lines. K-9 officer Aiden Murphy always kept things strictly platonic when it came to KCPD criminalist Lexi Callahan out of respect for her family's having taken him in years ago. Then Lexi is attacked during a crime scene investigation, and Aiden and his dog, Blue, step right in, making their relationship even more complicated. Keeping Lexi safe is his priority. But resisting the woman who's never been far from his thoughts will be his greatest challenge this holiday season.

This crime lab tech has enemies. And one wants her dead... A vicious hacker has KCPD lab tech Chelsea O'Brien dead in his sights, and Robert "Buck" Buckner won't let his personal heartbreak prevent him from keeping her safe. But the sparks between this reserved ex-cop and the warmhearted Chelsea are as hot as the trail they're tracking. Can their mismatched skills outwit a killer, and help them risk their guarded hearts?
