A range of Nilsson's works for young, developing and older readers are discussed, with a particular emphasis on The House Guest and There's a Crocodile There Now Too. Nimon examines the way in which Nilsson represents the world of children within picture books for children around twelve years old; a genre which has trouble drawing attention and popular acclaim. Nilsson also writes about 'writing for children', analysing how to read books and how to construct them (9) and is quoted as saying that fantasy 'can be way of presenting our human experience more effectively and memorably than it may be possible to do in realist fictions' (9).
