Duck Duck Ghost (Hellsinger, Band 2)

Sequel to Fish and Ghosts
Hellsinger: Book Two
Paranormal investigator Wolf Kincaid knows what his foot tastes like.
Mostly because he stuck it firmly in his mouth when his lover, Tristan Pryce, accidentally drugged him with a batch of psychotropic baklava. Needing to patch things up between them, Wolf drags Tristan to San Luis Obispo, hoping Tristan's medium ability can help evict a troublesome spirit haunting an old farmhouse.
With Wolf's sister handling Hoxne Grange's spectral visitors, Tristan finds himself in the unique position of being able to leave home for the first time in forever, but Wolf's roughshod treatment is the least of his worries. Tristan's ad-hoc portal for passing spirits seems to be getting fewer and fewer guests, and despite his concern he's broken his home, Tristan agrees to help Wolf's cousin, Sey, kick her poltergeist to the proverbial curb.
San Luis Obispo brings its own bushel of troubles. Tristan's ghost whispering skill is challenged not only by a terrorizing haunting but also by Wolf's skeptical older cousin, Cin. Bookended by a pair of aggressive Kincaids, Tristan soon finds himself in a spectral battle that threatens not only his sanity but also his relationship with Wolf, the first man he's ever loved.
