Memory Blank by John E. Stith

MEMORY BLANK (Ace

paperback, January 1986). An amnesia victim on a Gerard K. O'Neill- style L-5

orbital colony finds a tantalizing stranger for a wife, a wise-cracking

wrist-computer as an ally. As he tries to restore his wiped memories, he learns

things are far worse than he thinks. (See O'Neill's book, THE HIGH

FRONTIER, for a non-fiction treatment.) Reached the preliminary Nebula

Award ballot.
