London, in the not-so-distant future. Society has been divided into Pures and Crazies according to the results of a DNA test. But seventeen-year-old Ana, whose father invented the Pure test, has uncovered a recording with dangerous evidence that the tests are fake. Ana has escapes to the Enlightenment Project - a secluded sect living on the outskirts of the City. Back in the arms of Cole nothing is simple. Some in the Project believe her presence jeopardizes their safety, others interpret her coming as part of their prophetic Writings. When the recording Ana stole goes viral, the Project comes under attack. Now Ana's father isn't the only one looking for her. She's come to the attention of Evelyn Knight, the Chairman of the Board - a powerful woman with a sinister plan. Ana must take greater risks than ever to unravel the truth and discover the secrets that lie beneath the Pure test. But unlike her father, the Chairman doesn't want her safely home. She wants Ana's spirit crushed, permanently. And she will destroy everyone Ana cares about to do it.
