While in Sydney Tiff visited Booktopia HQ again to sign books and film another youtube video with John Purcell (above). She also got a behind the scenes tour. In the video, John continues his training as a ninja and takes on thicker wood this time. Because of Tiff's visit, Booktopia now have signed copies of Black Warrior for sale - but get in quick because stock is limited! Check out the blog on their website for more info.
