This might be his biggest coup yet! Legendary master thief Gideon Sable is on the hunt for the ghost of an alien-possessed man in this fast-paced supernatural heist thriller.

The Preserve in Bath - the British Area 51 - is the secret government dumping ground for all things supernatural and out of space. It is one of the most heavily-guarded places in the world. However, it''s not what protects it that makes it so dangerous but the things that are inside . . .

Gideon Sable - master thief, con artist and self-proclaimed vigilante - faces a challenge he can''t refuse. His client, the former Head of the British Rocketry Group, Professor Neil Sharpe, wants him to break into the Preserve. Once inside, Gideon and his crew of supernatural misfits can get any mystical artefact they desire out of the Preserve''s collection. The catch? To reach it, they must go through the treacherous Box Tunnel complex and not only face trained guards and booby traps but steal something that can''t normally be stolen - a ghost!

Sharpe''s obscure motive leaves Gideon uncertain and suspicious. The only thing he knows for sure is that he can steal anything with just the right amount of preparation - but will he be prepared enough to face whatever the Preserve holds, or will he find himself a permanent part of the government''s collection?

Not of This World is the fourth supernatural heist thriller featuring master conman Gideon Sable from British SFF veteran and New York Times bestselling author Simon R. Green, following The Best Thing You Can Steal, A Matter of Death and Life and What Song the Sirens Sang.
