I was the guy who always defended the book's ending, until our meeting at Dana's place in Tucson changed my mind
I used to get into it with anyone who trashed an ambiguous ending. Six months ago our club read a slim novel where the last page leaves the main character's fate open, and I spent an hour defending it as art. Then Dana pulled out her copy and showed us three earlier scenes where the author basically tells you what happens, and the ending just ignores all of it. I sat there with my coffee going cold and admitted she was right, it wasn't clever, it was lazy. Now when a book pulls that move I ask one thing before I defend it: did the writer earn the mystery or just run out of pages? Curious if anyone else has flipped on a book they once fought for.
What if the writer put those scenes in on purpose to mess with you? A book can set up one thing and then pull the rug out, and that gap is the whole point, not a mistake.
