Sacrifice: The Emergents Trilogy, Book 2 (Unabridged‪)‬

Captured by the group of rogue Emergents known as Hypnagogics, Kress and her Conspiracy search desperately for a way out of their confinement in a stadium-size prison-lab called the Mill. There, they find themselves subjected to a bombardment of psychological manipulations, physical challenges, and cruel techno-genetic experiments. Forced by the mysterious Auditor to endure a battery of mind-warping Virtual Reality missions and unsettled by a series of shocking discoveries, Kress and her friends will need to make agonizing choices and an equally painful sacrifice.
