A dedicated gamer, she throws herself into mersives to escape and is approached by a designer who asks her to play test his new game.It isn't like any game she's played before. Then a character she kills in the climax of the game turns out to bear a striking resemblance to a man who dies suddenly in the real world at exactly the same time. A man she discovers was one of those responsible for the death of millions on Earth.Disturbed, but thinking it must be a coincidence, Dee pulls back from gaming and continues the hunt for information. But when she finds out the true plans for the future colony, she realises that to save what is left of humanity, she may have to risk losing her own.
