He came to town to expose her.
But found a killer trying to destroy them both...
 
When human remains surface bearing the signature of Ruby Chen's own research, the forensic anthropologist finds herself connected to two murders she didn't commit. And squarely in the crosshairs of Seattle detective Callum Morrow. His best friend—Ruby's former coworker and ex who cost her everything—is missing, and the motive points to vengeance. But as attraction burns hotter between them, Callum uncovers new evidence revealing the trail of a cold-blooded killer they’ll have to work together to catch…before Ruby becomes the next victim.
