Sounds good! I might buy that. I'm into parallel universes, time travel, etc.
I'm still reading Harry Potter and The Goblet of Fire, am almost done, 80 more pages..at 734 pages, it's the longest book I have ever read! Harry Potter and The Order of The Phoenix is next, and hope to finish THAT before the NEW Harry book comes out in one month from today.
Doctor, have you read Poul Anderson's There Will Be Time? It's a good read about a man who can will himself backwards and forwards through time...
