Dementia — Michael A. Stackpole

YOU ONLY DIE TWICE
Cyril Dent is trying to recover from a horrible experience -- his own death. Resurrected and rebuilt by the high-tech MegaCorporation Cybertronic, his mind is now the ghost in a killing machine that is as resilient as it is deadly. But who was he before? Why did Cybertronic specifically choose him to rescue the severely traumatized Lorraine Kovan before another MegaCorporation or the Brotherhood's Inquisitors could interrogate her? And why does he have a psychic link with one of the Dark Legion's most diabolical minds?

Finding the answers could kill Dent again, for he'll have to weave his way through a tangled web of corporate intrigue, blast his way through Legionnaires, Necromutants, Heretics -- and come face to face with the most abominable force in the universe...the Apostle of War.
