I have so many books I've read and want to its taking up space in my mind and well.. paper.
Anyways I came across some sites recently that will do that for you!
Basically, fill up your inventory up with what you've read, want to, and what your in the middle of! I've tried both and I have to completely go with Good Reads, for me personally anyways. Their overall the same, but Good Reads just feels right.
Both sites also offer a drawing on ARC books too!
So check 'em out!
