New York Times bestselling author Steven Kotler crafts a near-future thriller about the evolution of empathy.

Hard to say when the human species fractured exactly. Harder to say when this new talent arrived. But Lion Zorn is the first of his kind--an empathy tracker, an emotional soothsayer, with a felt sense for the future of the we. In simpler terms, he can spot cultural shifts and trends before they happen.

It's a useful skill for a certain kind of company.

Arctic Pharmaceuticals is that kind of company. But when a routine em-tracking job leads to the discovery of a gruesome murder, Lion finds himself neck-deep in a world of eco-assassins, soul hackers and consciousness terrorists. But what the man really needs is a nap.
