Cliffhangers suck! Some authors are kind enough to mention if there's a cliffhanger at the end of their story. Others trick you into reading their book and bam! The story just ends leaving you pissed because it's a cliffhanger and now you have to wait for the next book to come out so you can find out what happens. Ever forget to pick up that next book? I have! Not all series end in a cliffhanger, but it would be nice if authors warned readers so they could make the decision for themselves if they want to read a book that has one.
