As Davey Milnes prepares to returns to the place called "Cloud Field", the truth about their involvement in the original experiment becomes more and more complicated. With missing team members and other groups unaccounted for; this parallel world holds onto its secrets. Davey goes back to find his friend Jared and the chief scientist Janey Amber. On his journey he meets Aiden who went missing ten years previously, and finds out more about why there is a part of each person that never really leaves the Sand Glass Experiment. Davey travels alone into a place where any action seems to be fatal and where giants guard the last shore on the edge of time. He finds answers to the mystery of life and death, and somehow comes back to return once again to our world. He rescues his friends and with the help of Marcia and others begins to understand that the experiment is greater than this one project, and they are all still a part of something called The Nimbus Project. The experiment is still running and is now working in multiple dimensions. No one can be trusted, not even your closest friends. And memory plays tricks with your perception of this reality.
