I use Mobilism
they take request. It's slightly (a lot) illegal if you don't like to break the law. I also use FreeBookSpot | Download e-books for free
I downloaded about 50 Urban Fiction books from there. If Moblism doesn't have it, Freebookspot does, and vice versa.
Use calibre - E-book management
to add the books to your kindle, Nook, phone, or any other reader you use. Calibre also converts books. You can go from .mobi (Kindle format) to epub (most other readers format). Calibre also stores your books, which makes it very easy to move books between computers, phones, and so on.
Hope this helps!
