Demon Magic and a Martini

This magical book follows a bartender who becomes an expert in different magical classes, including Demonica. However, her guild is strictly demon-free for good reason. When a demon is loosed in the city, her friends are determined to slay it, but even combat mages are out-magicked. The demon is hunting too, searching for deadlier prey among the mythics in the city. To unravel the sinister motivations, uncovering dark secrets and learning truths she never wanted to know becomes necessary.
