Raising Hell by G. Eilsel

What do you get when you cross an ancient spellbook, boxes of strange ingredients, and a giant, creepy rune carved into the attic floor?

A warlock, as Rory is quick to discover. With the rest of his life in shambles, he embraces his new identity. A few simple spells here, a couple of potions there, some charms to make life a little easier… no big deal.
Right?
His experiments with witchcraft lead him to a botched spell and a sassy—and sexy—demon houseguest that turns his world upside down. Rory’s limited magical knowledge means he’s scrambling to find a way to return him to Hell…
And all he wants to do is offer Rory a taste of Heaven.
