From the editors of American Book Review, we have this list of the 100 best first lines from novels.
Check them out. See if you agree. Personally, I think some of them were chosen based on the quality of the book rather than the quality of the line itself. Like this one, which was ranked #37:
Mrs. Dalloway said she would buy the flowers herself.
What's so special about that first line? I don't see it.
Suggest others if you like.
Thanks so much to Stidmama for the link!
