I want to know if you guys have any reccomendations

Most literary classics are free. I haven't really tried the modern free ones.

Project Gutenberg and their most popular books.

They offer tons of classic books as free ebooks for the Kindle and other devices.

Not sure what types of books to offer you though. It would help to know something about your favorite genre or authors.

Why not check out some Oscar Wilde?

"The Importance of Being Ernest" is his best play, "The Truth of Masks" his best Essay, "The Happy Prince" his best short story, and I'd go with "De Profundis" as his best work, period.

Books by Rice Edgar Burroughs, A Princess of Mars, Tarzan, etc. The Three Musketeers is another good one.

I second that. And Count of Monte Cristo too. And Adventures of Huckleberry Finn and Tom Sawyer. And Don Quixote. And Tale of Two Cities. And... Look I could go on but Project Gutenberg is a very good source of great public domain books.

For newer books:
If you like science fiction Baen Books (baen.com) offers some of its books for free from its ebook library.

Also, your public library probably has an ebook section that you can access from anywhere (provided you have a library card.

Edgar Allen Poe. If you haven't read The Raven, Tell-Tale Heart, Murders in the Rue Morgue, Pit and the Pendulum, Cask of Amontillado, I could go on and on.
Damn, now I have a hankering to read a few of his stories. Well I am almost finished with Under the Dome, so next up one of the classics.

Lord Dunsany. Gotta work on that nerd cred.
