Forgiving Chase by Cynthia Cooke

Jacquie Halloway is a cop who guards her heart as strictly as she guards her sidearm. Only now she’s forced to work with Chase McKenzie, the man who left her eight years earlier and never returned. Jacquie recovered and built a life without him, only now he’s back, and she’s in trouble, and worse his brother might be the one responsible.
As the founder and owner of Guardian Securities, Chase’s job is protecting his clients, but now he’s asked to protect Jacquie Halloway, the woman he once loved and left. Since he’s been gone, danger has moved into the small town he and Jacquie grew up in. The town he was forced to leave to protect his brother. The town he swore he’d never return to. Only now, his brother is at the heart of the drug crimes happening in Granite Falls, and Jacquie is in the crosshairs of a killer.

Can he stop his brother, and save Jacquie without losing his heart again?
