Nine by Zach Hines

In an alternate world startlingly close to our own, humans have nine lives—and they can’t wait to burn straight through them.

As you shed lives, you shed your awkward phases: one death is equal to one physical and mental upgrade. Julian’s friends are obsessed with the idea of burning lives, but Julian is determined to stay on his first for as long as he can. His mother, the ultimate cautionary tale, burned through her first eight in just a few years, and Julian has no intention of succumbing to the debilitating rebirth sickness that she inflicted on herself.

But the regime has death incentives aimed at controlling overpopulation, and Julian realizes that he’s going to have to burn at some point—especially when he becomes a target for Nicholas, the manipulative leader of the Burners, the school’s suicide club. And when Julian eventually succumbs, he uncovers suspicious gaps in the rebirth system that may explain exactly why his mother went so far down the rabbit hole years ago. Along with a group of student dissenters, Julian sets out to find answers and is soon on the verge of exposing the greatest conspiracy ever unleashed on the world.

He has just eight more lives to uncover the brutal truth.
