Does history have a ghost of a chance?

Eddie, Adam, David. Each has the same strange power: the ability to time-travel. Through portals of dreams, they can appear as ghosts, wherever and whenever they want. The first boy, Eddie, is the genius who has sworn to protect the past and uphold the dreamwalker's code. The second, Adam, is a haunter, a dream-terrorist, dead-set on changing history for his own nefarious ends. The third, David, is the neophyte who must fight for the future by keeping the other two apart! Can he surf the time warps, back and forth between 1940s London and today, to save the present from oblivion?
