Police officer Isabelle St. John loves her crazy, loud, law-enforcement family. She knows they'll be there for her when things get tough. Like when her partner is murdered and she barely escapes with her own life. Izzy is determined to discover exactly what happened, and her investigation sends her headfirst into a criminal organization, possibly with cops on the payroll--including someone from her own family. With her dead partner's brother Ryan, a handsome homicide detective, shadowing her every move, Izzy's head is spinning. How can she secure justice for her partner when doing so could mean sending someone she loves to prison? And how will she guard her heart when the man she's had a secret crush on for years won't leave her side?

FBI agent Declan Grey is in the chase of his life--but isn't sure exactly what he's chasing after. Threatened by a terrorist that "the wrath is coming," Grey fears something horrible is about to be unleashed on American soil. When his investigation leads him to a closed immigrant community, he turns to Tanner Shaw to help him. She's sought justice for refugees and the hurting around the world, and if there's anyone who can help him, it's Tanner. Tanner Shaw has joined the FBI as a crisis counselor . . . meaning she now has more opportunity to butt heads with Declan. But that tension also includes a spark she can't deny, and she's pretty sure Declan feels the same. But before anything can develop between them, they discover evidence of a terror cell--and soon are in a race against the clock to stop the coming "wrath" that could cost thousands their lives.
