Just read a pretty good book that was a decent enough in length to keep me occupied for a while: Peachtree Road by Anne Rivers Siddons. I give it two thumbs up, but caution (as always) not to read the prologue until you've finished the book. Why is it that "prologues" often seem not to contain backstory, but rather information regarding who might be alive or dead at the end of the book; why would you want to know the end going in?
In college I made the wise decision to skip the prologue of Lolita. As you may well know, it would have ruined the whole damn book. And so, as with Lolita, skip the prologue in Peachtree Road as well as any other book you might not want to know all the secrets of until you're done.
