Hi, Thank you for your enquiry. Unfortunately we are unable to provide any more information on products other than what is already available on the the products page. Many product pages also include customer reviews, which can be helpful in providing additional information about an item. If you need more information about a specific title, we recommend that you search for the ISBN (listed on the product page) using your favourite Internet search engine (eg www.google.co.nz). Kind Regards, Catherine
