Monsters: The King & Slater Series, Book 11

More money, more murder...

Heidi Waters, CEO of billion-dollar startup Vitality+, is all the rage in Silicon Valley. Her company's promises to roll out a neurochemical cure for caffeine-related anxiety are set to change the game, a godsend for anyone who's ever got the jitters from upsizing their morning coffee order.

Doesn't take them long to figure out that it's all connected…
