Excellent idea & nice execution too. Easy to navigate and I like that you allow for reviews of the book as well, this is always a big plus for me on book sites.

Kids books are a massive market, since they tend to get used for a couple of years then recycled. As the site grows (and I sincerely hope it does because it's a great alternative to the big sites) you might want to think about sub-categories for children. 0-2, 2-5 etc. Parents selling them will know which to put them in so it should be easy enough.

Hope this helps.
