That's right comics. WOWIO is a great place to register and get free books via PDFs. And YES. FREE. The system is structured so that the ads found within the books support the site, and the creators.
Why am I telling you this now? Well, I've been a member for a few months now, and recently they offered rewards for referrals. If 10 of you register and let them know that I referred you (using my email address, which is joshalves (a t) gmail (d o t) com (replacing "(a t)" with "@" and "(d o t)" with "." )), I get an iPod shuffle. Which means my wife gets an iPod shuffle. (She's a runner, and it'd be awesome for her to use). So yeah! Sign-up today!
