SSA Rain Christiansen used to be the agency's golden boy. It just takes one moment of weakness, one tiny paranormal sighting, and all of a sudden, he's the agency's embarrassment. His boss gives him one last chance to redeem himself - go down to Brickell Bay, play nice with the local police, and leave the ghost sightings behind. Rain is determined to do exactly that, even if it kills him. Cold-case Detective Daniel McKenna's latest investigation is going nowhere fast. Daniel is glad to finally have the FBI help his department requested, even if it does come in the form of his ex. 

No one said being a medium would be easy. Rain Christiansen, former FBI agent and current cold case detective, is starting to think it's the hardest job he's ever had - and the most important. He's determined to accept all the changes in his formerly well-ordered life, but that means embracing a whole lot of weird. There's no instruction manual for meshing his work with his medium duties, and he's painfully aware that he's flubbing the job. So are the ghosts, who are becoming increasingly impatient. And stronger.  

Rain Christiansen, cold-case detective and reluctant medium, is very aware of that fact. But when infamous serial killer Thomas Kane wants to meet, there's no way Rain can say no. He also can't refuse Kane's offer - find his missing wife, Delilah, and he'll reveal the location of his victim's bodies. Rain has never turned down a good quid pro quo, and he doesn't intend to start. The hunt for Kane's wife leads to yet another cold case, three copycat murders, and an investigation where nothing is as it seems. Soon, Rain is dealing with a ghost unlike any he's ever dealt with before.

Rain Christiansen isn't sure he'll ever fully understand the supernatural. But he's finally finding his groove as a reluctant medium and cold-case detective. That's not to say everything is going smoothly—there's a wedding in the works, after all. At least work is keeping Rain and the PTU plenty busy. The latest case involves Hannah Caldwell, a silent ghost who can't—or won't—speak. She still manages to request that they find her dear friend, Cherry Parker, so that she can say goodbye. Piece of cake. But when it comes to ghosts, nothing is ever quite what it seems. 

Rain Christiansen is settling into married life with fellow cold case detective, Daniel McKenna, and life is good. Better than good, even. But when it comes to the topic of expanding their family, Rain isn't so sure he's ready. Yes, a new addition could enrich their lives. But it could also tear down the delicate balance they've worked so hard to achieve. Do they really want to take that risk? He'd love to brood over that a little more, but murder never takes a day off. A decade-old mystery of the missing Parker family is heating up.
