Ubik

Psychic spies, half-life, and a mysterious product called Ubik are at the center of this deeply unsettling existential horror story. Glen Runciter runs a successful anti-psychic business, but when he and his team are ambushed, he is placed in suspended animation. As his surviving team members experience strange phenomena and the world deteriorates around them, they must unravel the mystery and discover the role of Ubik. A nightmare you will never be sure you've woken up from, this book is hailed as more brilliant than similar experiments conducted by Pynchon or DeLillo.
