Clive Cussler’s Desolation Code





The new white-knuckled thriller in the NUMA series from the No. 1 Sunday Times bestselling Grand Master of Adventure, Clive Cussler

A routine NUMA investigation uncovers a mystery, when a strange figure steals their findings. Who are they?

Meanwhile a cryptic text using NUMA's codes makes things still stranger: Are they being helped by a friend, or lured into a traitorous trap?

Kurt, Joe, and even Max, NUMA's supercomputer, will have to investigate like never before as they prepare for a battle on two very different planes: one physical; one digital.

It's just the beginning of a sinister plan concocted by a mind more brilliant than any they’ve ever faced—the mind of a machine. A new, terrifying world order is being plotted...
