Have you ever had an incredibly vivid dream? A dream so real that you can feel, taste and smell the world around you? Déjà vu is a feeling which all too clearly tells you that you're going somewhere you've been before, or experiencing something you know has happened to you already. Jacob knew that his weird dreams were much more significant than that. When Jacob suddenly realises that the life he's living isn't his only life, he will have to uncover ancient truths and the schism that changed mankind's history forever. He must determine the point at which the parallel world was created; the world the other version of Jacob inhabits. He must discover who is controlling these split universes and why, before it's too late.
