We are having a great time over at the Firsts Thread. Thanks, Jen! You are a brave woman and very hard working.
Although the entries have been met with interesting reviews, someone brought up a good point. They would hardly reject a book because of the first line. It made me wonder, what is your cutoff point? How far into a book will you read before you say, that's enough, I can't take this any more?
For me, I think a minimum of three chapters is enough. I feel this is enough time to establish the characters, the setting, and the conflict.
