Ahh! What a crazy simple but great idea. ;) I sometimes cringe after reading summaries on the backs of books when there's a huge spoiler. I think probably the author most of the time is not in charge of writing said summaries and it's dependent on the publishing company, but I don't really know.
Brilliant idea, I love books so much, but I don't know if I'd go so far. I generally try to find out the summary, even if I have to look inside a book jacket or something. :)http://anixstar.blogspot.in/
