Some things are worse than demons.

Jimmy Holiday, reluctant exorcist, is finally getting the help he needs from the higher-ups. The Order of Markers is sending him to the Vatican’s exorcism school. Now, he’ll receive the training he should have gotten at the beginning. One problem, someone wants to sabotage him.

When his time at the school is cut short, Jimmy receives an interesting new case. It is the assignment that no one wants—a corpse has come back to life. And it isn’t a zombie.

Too bad nothing goes as expected. Armed with his usual bag of tricks, Jimmy thinks everything will eventually be all right. Well, that is until his betrayer turns out to be the person he trusts most.
