Eddie, Adam and David have the same gift. Separated by generations,
they are linked by their ability to time-travel. Using their dreams,
they can appear like ghosts, wherever and whenever they want.
The first is the genius who discovers dreamwalking. The second is
a Haunter, a dream-terrorist, determined to change history for his
own ends. The last is the novice dreamwalker who must battle to
save his family, and himself, from oblivion.
