Curious about your personal blacklist: is it a personal thing with these authors or just their style and content? As far as avoiding or picking books based on summary - I do this all the time. I'm not a steampunk guy and certain things will turn me off so I avoid them. But to defend Kenubrion a bit, some people that have used summaries to avoid a book have also gone on to heavily criticize that book. That makes no sense to me. You can't heavily criticize a book and an author on second hand information imo.
