P. S. I Spook You

Once the agency's golden boy, SSA Rain Christiansen has become its embarrassment after a paranormal sighting derailed his career, and his boss gives him one last shot at redemption: head to Brickell Bay, cooperate with local police, and leave the ghost talk behind. Cold-case detective Daniel McKenna is glad for the FBI help his department requested on the five-year-old disappearance of high schooler Amy Greene — less thrilled that the agent assigned is his ex. As Rain and Danny dig back into the case together, old feelings resurface just as fast as the case's buried secrets.

S.E. Harmon opens The Spectral Files with a paranormal mystery-romance pairing a ghost-talking profiler with the ex-boyfriend detective he never stopped loving.
