Ghostv — Jordan Castillo Price

For the past dozen years, Victor Bayne has solved numerous murders by interrogating witnesses only he can see-dead witnesses. But when his best friend Lisa goes missing from the sunny California campus of PsyTrain, the last thing he wants to find there is her spirit.

Disappearing without a trace in a school full of psychics? That's some trick. But somehow both Lisa and her roommate have vanished into thin air. A group of fanatics called Five Faith has been sniffing around, and Lisa's email is compromised.

Time is running out, and with no ghosts to cross-examine, Vic can't afford to turn down any offers of help. An old enemy can provide an innovative way to track Vic's missing friend, and he enters into an uneasy alliance-even though its ultimate cost will ensnare him in a debt he may never manage to settle.
