Hi Richie, the book has been available to buy since May 26th. You can send me a personal message and, if you have a PayPal account, I can get the book to you for the weekend.
Amazon don't hold copies, which is why it's showing as temporarily out of stock, but they request them from me when orders are placed. So you can order from them with confidence if you'd prefer to purchase via them.
The book is due to receive some coverage in the next Martial Arts Illustrated, as well as Impact and Total Film.
I currently have 29 regular copies left, and four copies signed by the author Carl Jones. At this stage, I am not intending to reprint, so if interested get in quick before the MAI PR machine does its thing!
