In near-future NewBrit, where only Winners succeed, Maz Tallis is a Loser. All she wants is the expensive medicine that could save her half-brother, Kyle.

As her final term at Albion House Academy begins, Maz enters the Manticore Challenge, a competition offering the winner 1,000 Life Chances—credits that can be exchanged for life-saving treatments. For Maz, this could be her only shot at getting the medication Kyle so desperately needs.

To improve her chances of winning, Maz comes up with a bold plan. But when Felix, a charismatic Winner, steals her idea, they become fierce rivals. To make matters worse, Kyle gets a superbug, making the need for treatment even more urgent.

As Maz uncovers a disturbing secret at the heart of the competition, she faces an agonising dilemma: save her brother or expose the threat. Battling self-doubt and a corrupt system, Maz must decide if she will risk everything to reveal the truth. And will she find a way to save the people she loves without losing herself?
