What an interesting article! I don't think I ever thought about first lines, really.
Here are a few of my favorite books' first lines...
"Where's Papa going with that axe?" said Fern to her mother as they were setting the table for breakfast. --E B White, Charlotte's Web
Sophie couldn't sleep.
--Roald Dahl, The BFG
The morning sun shone brightly on the canvas of the covered wagon, promising an unseasonably warm day for mid-October. --Janette Oke, Love Comes Softly
Alex Stafford was just like Mama said. --Francine Rivers, Redeeming Love
It was a dark and stormy night. --Madeleine L'Engle, A Wrinkle in Time
