After reading Clare Langley-Hawthorne's post on the same topic over at The Kill Zone, I started thinking - what makes me stop reading a book? She came up with the topic after attending a panel at LCC (Left Coast Crime), which must have been interesting, and to be honest I'm envious and sad I couldn't be there.
The first thing came up right away: long, literally page-long, boring descriptions. Be it descriptions of the setting, the character, whichever. It is boring and it makes me fall asleep right away!
For another point I have to second Clare's "characters that make me a yawn". Oh yes, that is a big point on my list. It has to be! No matter how good the plot is, if the characters are boring or two-dimensional, the book just doesn't work. A book that is worth my time and doesn't end up being thrown at a wall has both a good plot and interesting, three-dimensional characters.
Big, fat plot holes would be another pet peeve of mine. I dump a book as soon as I see one and I'll never pick the book up ever again!
Changes of reality - I can live with a certain suspension of disbelief, but once an author re-creates basic truths without it being necessary for the novel. If you want to do that, state it on the cover, the back cover blurb or with the genre, but no single hint that it is science fiction or fantasy and yet you want to change the fact that in fact the sun is revolving around the earth? Yeah well, go search another reader for your book.
TSTL - granted, some Too Stupid To Live is okay, I can live with that, but authors who need TSTL to get the plot going and keep it going just don't do it for me. I'll drop the book, I just can't continue those books!
What about you? What makes you stop reading and put a book down? With what can an author turn you off? Tell me, let us know or check out the original post at The Kill Zone and comment there. Of course, I'd like it if you would comment both at The Kill Zone and here! ;-)
