How can I get free ebooks on stanza?

I recently learned that putting 'drinkmalk' into to URL as a catalog in the stanza app was a way to get good books for free. Then I found out that it no longer exists. I'm a teenager and am hoping that there is a way to get free ebooks that aren't classics or books that adults would like more. Any suggestions? Even if they are for other ebook reader apps. Please help!
