Crux: Nexus Arc Book 2 Paperback - 2013

“Potent like Naam’s vividly imagined nano-drug Nexus, Crux is a heady cocktail of ideas and page-turning prose. It left my brain buzzing for days afterwards.”
- Hannu Rajaniemi, author of The Quantum Thief and The Fractal Prince

“A blisteringly paced technothriller that dives deeper and even better into the chunky questions raised by Nexus. This is a fabulous book, and it ends in a way that promises at least one more. Count me in.” 
- Cory Doctorow, author of Little Brother

"Nexus and Crux are a devastating probe into the political consequences of transhumanism; a sharp, chilling look at our likely future."
– Charles Stross, author of Halting State and Singularity Sky

“Smart, thoughtful, and hard to drop, this richly nuanced sequel outshines its predecessor with a wide cast of characters and some complicated, uneasy questions about power, responsibility, and the future of humanity.” 
- Publishers Weekly

“Highly recommended for preparation of the future revolution.”
– Harper Reed, former CTO of Obama for America

“A brilliant book, full of mind-blowing tech drawn in highly believable fashion. Naam’s action sequences carry a brutal intensity, and every time you think he’ll finally let you breathe the stakes rise even higher.” 
- Jason M. Hough, New York Times best-selling author of The Darwin Elevator
