Cuckoo

Greg Summers is an ordinary man, in a mundane job, with a contented wife. Greg knows the answers to the questions. Until one day he doesn't. That day he returns home to discover that his wife no longer recognises him; that his wife is married to another man called Greg Summers. Perhaps it is an elaborate hoax, a conspiracy to unnerve and derange him. Yet that wouldn't explain the vivid flashbacks to his childhood, or the violent eruptions of blood that accompany them. Nor does it account for the stray memories that come to him from nowhere and seem to belong to an entirely separate man. A man called Richard Jameson.One of these men is a lie, and neither wishes it to be he. On the run from a creature that cannot exist, his comfortable truths shattered, Greg finds his whole knowledge of the world questionable. If he does not know himself, what can he trust himself to know? Greg Summers and Richard Jameson are about to discover that the fight to survive is all in the mind.
