Check out Daily Lit. It’s a site that e-mails you chunks of a book, at your pace. I’m reading The Jungle right now. It’s 170 parts long, and I’m a bit more than half way.
It’s a really simple way to read a book when you’re busy and don’t have a whole lot of time to sit down with a book. Most of the books are in the public domain, but that still leaves a lot of good books to read.
