Kayla lives in a world where the Virus has ravaged everything. It has taken the lives of billions of people, and taken away the ability to give it to millions more.
The world government, cornered, issues strict rules to fight the threat. This is the beginning of a new kind of dictatorship. For the survival of humanity, each person is obliged to submit to the Test, to be counted as Fertile or Infertile and marked according to the result.
Kayla refuses to trade her freedom for a Mark, to be locked up in a breeding facility or to work in camps for the comfort of the Fertile. She has never submitted to anyone, and she won't start now. Her only option is to run away and find the Resistance.
