Chain Reaction by Christy Barritt

When an explosion rocks Lantern Beach, authorities scramble into action. Was the WWII relic that washed ashore merely bad luck—or something far more sinister?

Dr. Raven Newton, a forensic archaeologist, is called to investigate the bomb that killed one person. With her specialized knowledge of military artifacts, she’s the perfect person for the job—until she discovers who else is on the case.
Former Navy SEAL Jake Laudner never forgot his whirlwind romance with Raven. Once assigned as her protector during a high-risk overseas mission, Jake broke his cardinal rule: Never get emotionally involved. Now working for elite security firm Blackout, Jake is stunned to find himself face-to-face with the woman who still haunts his dreams.
As the investigation intensifies, so does the tension between Raven and Jake. Raven insists their previous relationship was nothing but adrenaline and proximity. Jake knows differently—and he’s determined to prove it.

With a killer targeting Raven and time running out, she needs protection whether she wants it or not. And Jake won’t fail her twice, even if it costs him everything.
