Not all enigmatic authors are cut from the same camouflaged cloth. If J.D. Salinger wore his reclusiveness like a cloak, Thomas Pynchon wears his like Groucho Marx glasses. Far from eschewing modern-day life for an existence as a literary hermit, Pynchon is a pop culture sponge even at 76.

Pynchon is fascinated by how our lives are being converted ever more into zeros and ones. It’s fitting, then, that his latest is like the Internet itself: sprawling, centerless, weird, worrying, and often wonderful. A-
