Nighthawk by Clive Cussler & Graham Brown

A crashed spacecraft could destroy the planet

Very good condition – clean cover, sharp corners, spine tight

Flying over the South Pacific, the most technologically advanced spacecraft ever built vanishes without a trace, and both China and Russia would kill for the secrets locked inside it. Kurt Austin and the NUMA team are drawn into a stealthy race to locate the wreck before anyone else can, because only the United States knows what's really waiting in its debris: a payload of exotic matter, kept at near-absolute zero, so unstable that if it thaws it could obliterate the face of the Earth. With the clock ticking and rival powers closing in, the NUMA team will risk everything to stop the world's most dazzling technological breakthrough from becoming the very thing that destroys it. Clive Cussler and Graham Brown deliver a relentless, high-concept thriller in the NUMA Files series, with the fate of humanity riding on Kurt Austin's next move.
