I wrote a story called "For Want Of A Memory" in which I explored how amnesia can affect a person's life. In that book, a man could remember specific parts of an incident, but not the whole thing. Because he only had partial information, the decisions he made were flawed, in the sense that he'd have made different decisions if his memory had been whole. In the process of writing that book I realized there are other ways that missing or corrupted memory could affect a life. This book is an exploration of another of those ways.
