"It is the central core of an immense computer library -- an elite network of research planetoids. Here, the Pathfinders -- the only artificial intelligences legally permitted to serve the Federation -- control and sift the overwhelming dataflow from thousands of research vessels across the galaxy...

Now the greatest scientists in the Federation have gathered here for the prestigious Nobel and Z-Magnees prize ceremonies -- unaware that a deadly assassin is stalking one of them. And as Captain Kirk struggles to save his ship from sabotage and his first officer from accusations of murder, he discovers the hidden assassin is far from the deadliest secret lurking on Memory Prime... "

This is a paperback 1988 printing in used but very good condition

This is a pretty good book. Much better story than some Star Trek tie-in novels I've read.
