Demon magic and a martini
(Book)

"When I landed a job at the local guild, I didn't know a thing about magical classes. Now I'm practically an expert, but there's one nobody ever talks about: Demonica. Turns out they have a good reason for that. Some people will risk life and soul to control the biggest bullies on the mythic playground--and now a demon has been loosed in the city. My three best friends are determined to slay it, but even badass combat mages are critically out-magicked. And that's not all. The moster they're tracking--it's not hiding. It's not fleeing. It's not leaving a trail of corpses everywhere it goes. The demon is hunting too. And in a city of mythics, it's searching for deadlier prey. If we can't unravel the demon's sinister motivations, more innocent people will die, but finding the answers means digging into dark secrets...and learning truths I never wanted to know" -- back cover.
