Leaving the Army behind, Chase McConnell works for a fellow military buddy at ARC Angel Protection. When strange notes start to arrive at the New York office, and one mentions him by name, he’s sent there to work a case. But he arrives to find the note isn’t the only thing he has to confront when he comes face to face with his estranged childhood best friend…and his biggest regret—his friend’s kid sister, Lizzie—the woman he scorned almost a decade ago.

Thanks to traumatic high school experience involving her brother’s best friend, Lizzie Foster has been battling self-esteem issues and anxiety for years but living in a bubble isn’t living and she’s ready to move forward and make a difference. When a new job opportunity arises at her brother’s workplace, Lizzie eagerly accepts the position. Too bad her brother neglected to mention her partner for her first case is the guy who broke her heart and stole her self-worth.

Their only hope in solving the case lies in their ability to face their past to work together as a team. Confusing notes, lack of leads, and a strong attraction top their list of challenges.

Now the chase is on to convince Lizzie he's sorry for his juvenile actions of the past. But when she turns up missing, he vows to find the woman he loves so he can spend the rest of his life showing her just how much she means to him.
