A chilling take on the opioid epidemic by the New York Times bestselling Neal Shusterman and Jarrod Shusterman.

Above our world is a toxic wonderland where the party has raged for centuries.   

Humans know the partygoers simply as  narcotics, opioids, drugs. But here they are malevolent gods, toying with the fates of mortals. Roxy and Addison have made a wager to see who can be lethal the quickest.    

Isaac and Ivy Ramey are their targets. Ivy is understimulated and overmedicated. Isaac is desperate to recover from a sports injury that jeopardizes his chance of a scholarship. This is the start of a race to the bottom that will determine life and death. One Ramey will land on their feet. The other will be lost to the Party.   

The only question is… Which one?
