From Shock Till You Drop:
"Travis is a young psychiatrist on the brink of a nervous breakdown after the death of a patient to whom he was inappropriately close. But his life appears to take a change for the better when he meets Grace, a mysterious teenager and the representative of a secret church that promises salvation to even the most troubled of its members.
Intrigued, Travis joins the group and meets its leader, the charismatic Father Jay, who indoctrinates him into the sect's sometimes radical practices. But when a series of tragedies befalls Father Jay and his flock, Travis must decide if his loyalty truly lies with Father Jay, the ever-elusive Grace, or himself."
