The life of Dr. Theo Reynolds is consumed by the past. As an archaeology professor at Harvard, Theo spends every waking moment studying it... Just not her own. Her reluctance takes a back seat when she's offered a consulting job with the Maine State Police after an unmarked grave with human remains is found. It's her big break. The chance to lead her very own dig site. The catch? It's under the supervision of her old high school crush.

Detective Lewis Hawthorne lives a quiet cautious life, despite investigating homicides for a living. He dotes on his nieces, shows up for his friends, and focuses on doing his job well. He likes the routine. He's happy in it. Content, at least. Until Theo Reynolds rolls into town to consult on one of the strangest murder cases he's ever seen and digs up old feelings along with artifacts.

Tensions run high as Theo and Lewis try to navigate professional boundaries, buried emotions, and connect the clues that might eventually lead to a second chance at a romance that never was.
