So a really smart rule to follow is never to summon anything larger than your head. Unfortunately, a bunch of cultists decide to summon up the Antichrist and get more than they bargain for. (And isn’t that supposed to be God’s decision in that mythos as to when the Big Evil Guy shows up? Geez, know your myths before you start screwing around with them. Silly cultists.) Not only is the Big AC, you know, evil, but that brings the Nuns Without Guns onto their cases.
The book works and doesn’t require you to be Catholic or even a believer of any kind–the nuns take themselves more seriously than the situation warrants and that’s all that matters. So if you can roll with that, you’ll enjoy it. It doesn’t break any new ground with its superheroines in habits routine, but it wasn’t meant to. It’s just a fun read. It will be out from Viper Comics later this year.
