"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? -- adapted from Goodreads info. Provided by publisher.
