One line I remember from a book title I've forgotten:
"Somebody said 'true love is like ghosts which everyone talks about but few have seen.' I've seen both and I don't know how to tell you which is worse." Can't remember the name of this book, but the author's name starts with G and there's a picture of the corner of a white house on the cover. Plus, it's a quote within a quote and the part starting 'true love is like ghosts which everyone talks about but few has seen' is adapted from La Rochefoucauld. [edited - the book is More Than You Know, by Beth Gutcheon.]
Do you have any favorites: I've left off some of the most famous ones - Pride and Prejudice, Emma, Huckleberry Finn, Rebecca, Tale of Two Cities, War and Peace, etc.
