True terror comes from deep within.

Dr. Lydia South, a cutting-edge neuroscientist, has perfected a lucrative, top secret technology that can map secrets of the brain. But Lydia’s past is inextricably bound with that of a brilliant but deranged sociopath, a man with the ability to blend in anywhere around the world, sow seeds of destruction, and escape unscathed—and he’ll stop at nothing to remain anonymous.

It’s a dizzying case for the straight-shooting Lt. Elliot Elliot, aka E-Squared or Double E. As the former cop untangles the madman’s cleverly constructed web of false leads and dead ends, he’s drawn deep into the human mind—and even deeper into the mind of a monster. And the only hope for Elliot and Lydia escaping alive may rest in the unpredictable hands of an inexplicably gifted four-year old boy.
