Sometimes you can predict the end of a book while you’re still in the middle – or even the beginning.
It’s a little disappointing to be able to accurately to predict in the beginning – the book has barely gotten started, and if all goes as predicted, what’s the point?
Or maybe it’s not; if the couple doesn’t get together at the end of a romance, that would be odd. Or if murderer isn’t caught at the end of a murder mystery, that would also be a bit odd.
But aside from that! Unexpected things have happen in between those things.
If they don’t, I am pretty sure I would be bored.
