Two siblings get caught up in a wager between two manufactured gods, Roxicodone and Adderall, in this new thriller inspired by the opioid crisis. Isaac and Ivy Ramsey are the victims of the bet between two manufactured gods: the seductive and lethal Roxy (Oxycontin), and the smart, high-achieving Addison (Adderall). The wager: a contest to see who can bring their mark to a rave that has raged since the beginning of time. Drawn by what the drugs offer, tempted to take that step past helpful to harmful are Isaac, a soccer player thrown into Roxy's orbit by a bad fall; Ivy, his sister, whose increasing frustration with her untreated ADHD leads her to renew her acquaintance with Addy. One will land on their feel; the other will be lost to the rave. The question is: which one?
