Like a modern-day Oz story – the books, not the movie. You’re picked up by the author’s whimsical tone on page 1 and gently put down a book later. The halfness of the title refers to the fact that to save her live, the heroine’s legs are replaced by trees. It makes perfect sense in the context of the story. With perfect plot logic, she learns not to stand around too long on damp ground in case she starts putting down roots … In fact, the whole plot is utterly logical, for a given brand of logic that is described as it goes. The fact that it’s also about coming of age, friendship, yadda yadda yadda is icing on the cake.
