Here are a few to get you started. There all from books I've read recently and enjoyed.
A) Stella tried to ignore the aroma from the hotdog stand as she bounced along in time to the rock music blaring from the dodgems.
B) "You do see, don't you, that she's got to be killed?"
C) You might think he could have made up his mind earlier, and been man enough to tell the others of his decision.
D) The old lady had changed her mind about dying but by then it was too late.

If you recognise the book you can still 'guess' the genre, but please don't give away the title just yet. I'll reveal them in a couple of days.
ps, if you use the opening line to one of your novels as your question, please give your question a number. Then email me with the number and a link to where the book can be bought and I'll include those in the answers.
Louise Wise is also running a competition connected with novel writing. For hers you are asked to write a 500 word short story, which could be a spin off from your novel. As a prize she's offering to buy and review your book and to feature you on her blog.
