There is a great holiday in the world. The gods - “substances” - celebrate. Hiro, Coco, Mary Jane and others. They come down to earth to seduce people. But they cannot come down on their own initiative - people must call them. And people are calling. And then they cannot escape from the suffocating embrace of the “gods.” The good boy Isaac fell for the bait of Roxy (OxyContin, a powerful analgesic that causes terrible addiction). His sister Ivy, who suffers from attention deficit disorder, is on Adderall. How brother and sister fight with the “gods”, who wins and who loses in this battle, how the “gods”, who are actually demons, charm humanity and lead it to destruction - that’s what this book is about. Neil Shusterman and his son Jarrod raised the topic of opioids in the United States. Doctors prescribe strong sedatives and painkillers to patients, which are addictive. The scale of abuse of these drugs is such that there is now talk of an epidemic.
