Book - Once there were giants

Would anyone happen to know where I could get a copy of the book once there were giants. I have look in amazon and its over £20!! Is there anywhere to get it a little cheaper?

try bookdepository.co.uk - free delivery to Ireland also

thanks had a look there and there are none available. they are pretty pricey then in the other links provided. If anyone has this book for sale I would be really interested.
