From the author of the international bestselling thriller The Apollo Murders: a supersonic hunt for a shadowy Soviet defector known only as 'Grief'.

Israel, late 1973. As the Yom Kippur War flares into life, a state-of-the-art Soviet MIG fighter is racing at breakneck speed over the arid scrublands below...and promptly disappears.

It soon becomes clear to Israeli intelligence that the pilot is a defector, desperate to come over to the US side. Houston Flight Controller and former test pilot Kaz Zemeckis is charged with bringing the pilot and his plane to the highly secret Area 51, in the Nevada desert. But every defection carries with it a risk. It soon becomes clear that 'Grief' has the technical ability, and now the opportunity, to gain access to the treasures of the Nevada Test Range - either a prototype stealth fighter or the NERVA nuclear rocket engine. Or both.

For Chris Hadfield's second heart-stopping thriller, we move from Space to another rich and exciting part of Chris's professional CV: his time as the top test pilot in both the US Air Force and the US Navy, and as a Cold War pilot intercepting armed Soviet bombers in North American airspace. Just as Gregg Hurwitz called The Apollo Murders 'an explosive thriller by a writer who has actually been to space and back', here we have a matchless thriller and the nerve-shredding rush of aerial combat, as told by one of the world's top fighter pilots.
