Flex by Ferrett SteinmetzRead about the other entries on the list.
Flex is set in an urban fantasy world in which the titular magical drug is a crystalized form of luck. You snort it, live a charmed life while high, and face a proportional amount of bad luck when you finally crash. When one father turns to Flex to heal his burned daughter, he runs a gamut of drug dealers, brain-wiping authorities, and the dangers of the drug itself. That’s right: this is basically Breaking Bad meets The Dresden Files.
