5.75" x 8.5", 380 page hardcover with dustjacket titled THE MESSIAH CHOICE by Jack L. Chalker/ Bluejay Books, ISBN # 0-312-94301-6,  First Bluejay Printing, May 1985 / A 15-foot-tall invisible monster... A cybernetic SAINT... a quadriplegic angel... A superpowered corpse... A computer programmed by Hell... Sir Robert McKenzie's Island was a heaven for cutting-edge research - until black magic was bonded to science, and the Dark Man appeared. He had the power to grant wild wishes or annihilate at a whim, mold bodies like putty, shatter brains, twist time. Detective Gregory MacDonald and a beautiful, paralyzed heiress from a convent, Angelique Montagne, knew the total horror spawned in a Caribbean paradise: that the Anti-Christ was risen. And only a handful of humanity stood between him and Armageddon.
