Memory Blank

Imagine what it must be like to be Cal Donley. He regained consciousness on the orbital colony Daedalus. It's a beautiful place, home for more than a million people, but Cal doesn't remember leaving Earth. In fact, he can't remember his name or most of the past dozen years.
What disaster has stripped away so much of his memory? Why? And what about the dried blood on his hands?
In the realm of novels, John E. Stith's Memory Blank...is a good solid mystery, a good adventure, and even a good science-fiction novel--all between one set of covers.-- STARLOG
