Magic for Dummies by Lacey Carter Andersen

Three things I didn’t know yesterday:
1. The old gods still exist.
2. They can inhabit a human body… like mine…when a girl is just innocently studying at the library (and maybe stealing one small microfiche…)
3. The old gods are cruel and dangerous and oh, also, horny.
Actually, add a fourth thing: There’s a reform school for delinquent supernatural creatures.
After a little mishap where I may have accidentally set my school on fire, I have to choose between human prison or a paranormal academy for the troubled. I look terrible in orange, so it’s a simple call…
But it turns out, all the bad boys of the supernatural world… vampires, shifters, witches… can stop fighting each other in the yard at God Fire Reform School and agree on one thing. They want the gods dead and gone again.
I’m not going into this twisted new world alone though. The four boys I once loved, who have grown into sexy men, are all possessed by the gods. Not only have we inherited their powers, but a shard of their troublesome personalities, too.
Which means even we’re scared of what we might do next… If these men and I don’t master the gods within, this school won’t ‘reform’ us. It will bury us.
