Into The Labyrinth (The Death Gate)

New York Times bestselling authors Margaret Weis and Tracy Hickman have earned
international acclaim for their fantasy novels. After eight years of successful collaboration, there are now over ten million copies of their books in print around the world.

In the Death Gate series, Weis and Hickman have created their most exciting and original epic to date. Into the Labyrinth, the sixth of seven books set in the vast and richly imagined Death Gate Universe, is a romantic and heroic tale that spans four worlds in an age-old battle to control the sundered realms of air, water, fire, and stone...

Xar, Lord of the Nexus, has traveled to the fiery world of Abarrach to learn the secret art
of necromancy, hoping to raise an army of the dead to conquer the four worlds. But he
discovers an easier way. One of the undead tells the lord about the Seventh Gate, the
magical chamber used by the Sartan to sunder the world. The Seventh Gate still exists and whoever enters it can either create worlds - or destroy them.

Only one person knows the location of this gate, although he doesn't know he knows it.
That person is Haplo.

Xar sends a Patryn assassin to kill Haplo and bring back his corpse. The lord plans to use his necromancy to bring Haplo back to life and turn him into a mindless slave who will reveal the location of the Gate. Xar is certain of success, for the assassin is someone from
Haplo's past. someone whom Haplo trusts with his life.
