When Louise Somerville’s new Mentis A3 serum goes to human trials, Kai and his friend Logan are among the first to be tested. The results are revolutionary, with effects ranging anywhere from minor empathy to complete mind control. But, as it becomes clear just how powerful and dangerous MA3 is, Louise disappears, taking the serum and all of her notes with her.
Kai tasks himself with hunting down Louise to return both her and the MA3 research to the Institute. Following months of fruitless searching, a promising new lead in Glasgow brings Kai closer to discovering Lousie. He will learn how desperate she is to remain free, and how lethal she has become when he uncovers a devastating truth.
