We would like to start publishing new editions of amazing classic novels that are timeless and inspired us. What are your favorite classic books?

"Catcher in the Rye" ♥ ♥ ♥ J. D. Salinger.

And G. H Wells, esp. "War of the Worlds"

Jane Austen's books ;) (she'll always be my favourite and her books are constantly reprinted, filmed etc.)
Dickens' The Pickwick Papers
Hawthorne's The Scarlet Letter

I loved "Crime and Punishment" as well as "The Master and Margarita".

Maybe you should consider adding other gothic and horror classics? Edgar Allan Poe's work would be a great choice. Adding H.P. Lovecraft's stories would also be a great idea, however, it might be tricky due to unclear copyright status of his works.

The Adventures of Huckleberry Finn by Mark Twain
Also you can't go wrong with HG Wells.
