When I was little we used to make Sally Worms to count the days down to an exciting event. You tear a segment off each day. This is my Sally Worm, or shall we call it a book worm, that is helping me count the days until Elin’s Air becomes avaliable for purchase. 25 days to go. Although having said that, it will be available slightly earlier from Waterstones, where you can pre-order a copy.
