Otherspace

From the back of the book: Beyond realspace, past the time-bending corridors of hyperspace, another galaxy waits to be discovered. When a problem develops with the hyperdrive engine of an Alliance prisoner transport, members of both the Rebellion and the Empire are deposited into a strange, unexplored dimension between the hyperlanes and realspace. Here abandoned ships from all over known space float beside those of unknown origin. These desolate craft orbit a giant vessel, drawn to it like moths to a flame - or a spider's web. Within the dark interior of the giant ship, the war between Rebel and Imperial finds new weapons with which to destroy each other, but they also find something else, something that just may find them first. It wants to escape otherspace, to reach realspace, and when it does, the galaxy will die!
