A compulsively readable novel
Iain Pears
A genuine treat, with its sneaky plot and richly textured storytelling. It also moves so fast that readers won't realize how smart it is
San Francisco Chronicle
<i>Codex</i> takes its place on the shelf [with] <i>The Name of the Rose</i>, <i>Possession </i>and<i> A</i> <i>Case of Curiosities,</i> and it's as entertaining as any of them
New York Times
Fabulously entertaining ... By turns fascinating, compelling, and deliciously disturbing. It's an intelligent thriller that truly is just that: intelligently thrilling
Boston Globe
Mesmerizing from start to finish ... A fabulous double-helix of a novel
Baltimore Sun
