Andy Griffiths & Terry Denton's The 52-Storey Treehouse has won the Nielsen BookData Booksellers Choice Award

Andy and Terry's incredible, ever-expanding treehouse includes a life-size snakes and ladders game (with real ladders and  snakes), a rocket-powered carrot-launcher, a Ninja Snail Training Academy and a high-tech detective agency, which is lucky because they have a BIG mystery to solve - where is Mr Big Nose??? The award was announced at the Australian Booksellers Association’s ‘Celebrating Bookselling’ dinner and awards night on 17 May.
