Clive Cussler Desolation Code is the 21st installment in the NUMA Files series, written by Graham Brown and continuing the legacy of #1 New York Times-bestselling author Clive Cussler. Published by G.P. Putnam's Sons (Penguin Random House) in November 2024, the hardcover edition runs 400 pages.

When Kurt Austin and Joe Zavala of NUMA investigate a mysterious mass stranding of aquatic life in the Indian Ocean, they stumble upon a conspiracy far larger than they could have imagined. A shadowy figure steals their findings, setting off a high-speed chase that pulls them into a web of bio-hacked sea locusts, a sinister cult, and a chilling new threat: a rogue artificial intelligence plotting a terrifying new world order. Racing against time, Austin and Zavala must decrypt cryptic messages, infiltrate a dangerous organization, and stop a machine intelligence before it rewrites the future of humanity.

Graham Brown is the coauthor with Cussler of Devil's Gate, The Storm, Zero Hour, Ghost Ship, The Pharaoh's Secret, Nighthawk, The Rising Sea, Sea of Greed, Journey of the Pharaohs, and Fast Ice. Available in hardcover, trade paperback, mass market paperback, large print, ebook, and audiobook formats.
