Basically, you just answer some questions about what you read, what you write and things, submit it. Then i'll match you up with another person who has written a book in the genre you read. You then read then book, post a comment, vote if you like, and send them some critique about the story, vice versa. its all very simple. You'll be given a week to read at least 4 chapters if there are that many. If at then end of the week you haven't read the book and given the appropriate feedback, without alerting myself or the person who's story you are reading, you will be taken off the list.

This is just a good way to get your stories read :)
