Shout-Out: Last Call at the Nightshade Lounge by Paul Kreuger

College grad Bailey Chen has all of the usual new-adult demons: no cash, no job offers, and a rocky relationship with Zane, the only friend still around when she moves back home. But her demons become a lot more literal when Zane introduces Bailey to his cadre of monster-fighting bartenders. It turns out supernatural creatures are stalking the streets of Chicago, and they can be hunted only with the help of magically mixed cocktails: vodka grants super-strength, whiskey offers the power of telekinesis, and tequila lets its drinker fire blasts of elemental energy. But will these supernatural powers be enough for Bailey and a ragtag band of mixologists to halt a mysterious rash of gruesome deaths? Includes 13 cocktail recipes from an ancient book of cocktail lore.
