Thanks!
Thanks so much for the kind words, Sam Beckett Fan - it's really nice to hear that a reader enjoyed the book.
Actually I did want to bring Sam home at the end of the final book, but the publishers set down an ironclad rule that he could NOT come home, in case a movie cropped up someday. (We're still waiting...!) So I thought it would be interesting for the final book to lead right into the final episode. Originally the book was called "Balance of Power," but when I came up with the idea for that last chapter at Al's bar, the editor said she'd like the title to include the word "Mirror."
To expand on things...there was a rule from the publisher all along that we couldn't change anything drastically. They said we could bring in another sibling for Sam, or give Al another wife, but at the end of the book things had to be restored to their original state. (Like, the Leap could change Sam's or Al's history while it was happening, but when the Leap out happened, things returned to normal.)
So I felt bad for the readers who were upset that Sam didn't return home, given that the book was billed as "the final adventure" or some such thing.
More on the ending...people have complained about it, saying that it still left a lot of holes, a lot of questions unanswered. Yes, I know.
The reason is that I was writing under a very tight deadline. The book got off to a slow start for personal reasons (not my own), so finishing the book was a serious crunch - remember, I was working full time, and could only write evenings and weekends. I came up with an ending, submitted it, but wasn't happy with it. Neither Ginjer (the editor) nor I could come up with a solid way to fix things. I tried several drafts, and none of them really worked. So we had to settle for "this is the best I can do in this time frame." If I'd had another couple months to do a few more drafts, the story probably would have been tighter and the ending somewhat more satisfying.
And a comment to the people whose response to "Obsessions" was "Sam doesn't do anything! He doesn't DO anything!" Well...yes. Because the story is about AL. (And the others at the Project.) The idea was for Sam to sit at the cabin feeling frustrated, and for the reader to feel frustrated FOR him. So in that sense, I guess it worked.
More comments are welcome, and I'm glad to answer any questions.
