“A book with top-level political threats, an ages-old conspiracy and a lot of codes cannot escape comparison with The Da Vinci Code. However, Tetraktys reads like a scientist’s revenge: popular fiction doesn’t have to make nonsense of science, does it?” (Rating: “Excellent”)

–ZDNet UK, Wendy Grossman

“Juels laces Tetraktys with many of the ‘what if’ scenarios that keep cryptographers up at night … The novel adds Juels to a handful of security specialists using fiction to hash out potential security hacking scenarios for coming years.”

–Boston Globe, Mark Baard

“As a novelist, Juels’s style approaches that of Umberto Eco … Tetraktys is a remarkable work of fiction…”

–Slashdot, Ben Rothke

“Code-breaking, forgeries, murder, romance, ancient Greek cults brought to life, three-letter agencies defending national security–what more could one want? A compelling tale, well told!“

—Prof. Ronald L. Rivest, M.I.T., the `R’ in RSA
