Warning, it has MAJOR SPOILERS in it if you haven't read Undine which, you know you could buy at Amazon if you want the exciting hardback or at Dymocks if you want the beautiful Australian paperback. And guess what? It makes a GREAT Christmas present. But you better buy Breathe too (sorry US edition is not out till February...but I am sure that Dymocks ships world wide).
Here are some non-spoiling excerpts from nice review:
This is a genuinely lovely novel. The writing style is elegant and evocative; it has a sort of dreamy remoteness that casts a patina of other-worldliness over the novel. At the same time, it is strongly rooted in reality; if the magical elements had been abstracted from this novel, it would still have been a powerful and effective story of a young girl struggling with the challenges of adolescence.
