Crosstime
An orphan, Blake Walker has never really known who he is, and his
strange flashes of intuition have always set him apart from those who
raised him and everyone else he has known. Acting on one of those
flashes, he prevented a murder. But neither the assailant nor his
intended victim were from the world Walker had always known, and he had
stumbled onto the greatest secret of the ages. Our Earth is only one of
an infinite number of Earths, each with a slightly different history
from the others, each separated from the others in a crosstime
dimension. Walker was drafted into a frantic search for a madman from
an advanced Earth who desires to be an absolute ruler of men. The
would-be tyrant has chosen our Earth as the place where his reign will
begin. And, if the powerful technology he controls does not give him
complete control of the planet, he will not hesitate to destroy it
utterly.
Publisher's Note: Crosstime was originally published in two parts as The Crossroads of Time and Quest Crosstime. This is the first time both novels have appeared in one volume.
