Joy Shall be in Heaven

A Guardian Angel to serial killers

His newest Charge

And a grimoire with a Free! Demon! Inside!

Nachumiel's job is to be the Still Small Voice whispering into the ears of sociopaths, in a vain attempt to turn them from the path of destruction they're merrily traipsing down. Fresh off yet another assignment up to his hips in blood and buried in corpses, he's beginning to wonder if he garners assignments like this because he's a massive screwup who can't damage these people any more than they already are.

His new Charge is different—but not in a good way. Gerry finds a malevolent spellbook holding a demon bound within, whose power even other demons are afraid of. Now Nachi has to team up with his argumentative opposite number and endeavor to undermine both Gerry and his damnable new friend before a child is sacrificed and the grimoire demon unleashes Hell on Earth. All he can try is what has always failed in the past...

And hope he doesn't end up bleeding out on the floor himself.
