After flunking out of the Auditor training program and being dismissed as “not Department material,” Grimsby tried to resign himself to life as a mediocre witch. But he can’t help hoping he’ll get another chance to prove his skill. That opportunity comes with a price when his former mentor, aka the most dangerous witch alive, is murdered and Grimsby is the Auditors’ number one suspect.
Proving his innocence will require more than a little legwork, and after forming a strange alliance with the retired legend known as the Huntsman and a mysterious being from the Elsewhere, Grimsby is abruptly thrown into a life of adventure. Now all he has to do is avoid the Auditors on his trail, find the real killer, and, most importantly, stay alive.
