It always amuses me when annotation to the book ends with something like:
"She will find ....(insert hope, love, a shoe etc) or will she find her death?"
"His\her secret will lead to their deaths..."
"She'll find out just how dangerous it will be..."
"blah blah blah, or will it cost her her life?"

And other creeptastic lines like that, I understand that they set up the intrigue, smth to lure the reader, but I can't stop rolling my eyes everytime I read smth along these lines.

Oh, there's another thing that I usually don't like in books, when the chapter ends with something like:
"But they didn't know yet, that everything will go downhill from there..."
"And that would be the last time they will feel so happy..."
"They had no idea that everything was about to change drastically..."

And other lines that predict impending doom. Why? Why? WHY do you need to spoil their happy times for me? I don't wanna know beforehand that the shit will hit the fan, I don't! It's not gonna make me turn the next page faster.

And the last, but not least, cause it always makes me laugh, is annotation that goes like:
"She (usually it's some poor schoolgirl) knew she didn't belong, and all she wanted to do was to graduate as soon as possible and live a simple quiet life so that no one would know that ... (insert she was half-fairy\a witch\a dragon\a werebug\had some super freakish abilities etc.) But then this mysterious guy transfered to her school and suddenly she was drawn to him and..." blah blah blah he had some secret that she just had to know, and of course he was interested in her and he will become the cream to her coffee or whatver but they will unleash a ton of problems before be together and blah blah... MY GOD! I see annotations with this same plot so often, it just baffles me - CAN'T THEY COME UP WITH SOMETHING MORE ORIGINAL???? Gah!
