Goodreads

Are any of you (authors) registered with Goodreads?

I'm registered as their authors. You can offer giveaways and invite people to events there. I find it really useful to spread the words about my books.

But one thing most interesting is you can check out who have listed your books as "to-read" or who have given your books a rating and reviews.

I found that for my first book In Quest of Theta Magic, a paranormal romance without any obvious relation to Pride and Prejudice, I received more higher stars rating from men, than from women.
