What is bookarmy?

From the horse's mouth:

...a social networking website for every sort of reader. Whether you’re a bookaholic or someone who picks up a book only once a year while relaxing on holiday, bookarmy is the place to discuss and review books, build reading lists, get the best book recommendations, and where you and your friends, family or classmates can read books together.

What makes bookarmy different from other book sites is that here you can make direct contact with authors; see what star rating they have given books, browse their reading lists, ask them questions about their own writing, and recommend titles to them.

I searched "Marcus Sakey". No one had yet reviewed any of his 3 books. I registered and provided a brief comment on "The Blade Itself". Haven't seen it posted yet.
