For most of the book this is a delicate and beautifully poised piece of writing, a tale seen through the eyes of a young girl on the edge of womanhood. Various older myths and stories surface in the story - the strange and haunting house, which gives and takes hints at Hansel and Gretel, the sense of trembling on the edge of meeting the first soul-mate/sexuality like a modern, female take on Le Grand Meaulnes (horribly retitled in translation as The Lost Estate - I have only ever read it in translation, but when I first read it, the original French title, the name of the 'hero' was considered good enough!) There's also a sense of menace brooding over all, from an adult outside presence, a ghostliness that also reminded me of Turn of The Screw - that sense of unseen menace which you are never quite sure is in the mind of the central character only, or is outside reality. And the little band of wild children, particularly 'Mouse' is quite Peter Pan/Lost Boys, with Mouse as the anarchic Tinkerbell.
Myerson is brilliant at getting inside the mind and heart of the damaged and fragile child and adolescent; indeed into adolescence itself, where so many identities are warring to be born within any one individual.
From about 3/4 of the way through the book I started to pull outside its spell, and began to wonder 'how on earth can she find a satisfactory end for this' - there was such a delicate poise between 'reality' and the darkly magical that it felt as if coming down on one side or the other would feel like a huge let down. And it did. No spoiler, so you'll have to read it to find out, but to me it felt like her sure touch faltered and an ending was found which wasn't in the life of the book as a whole. To be fair, I have absolutely NO idea what a satisfying ending could have been - in many ways, I think it should have LACKED a resolution, and ended in a way which left us all wondering 'is this real, is this fantasy'
Though the ending was a disappointment, the bulk of the book was wonderful.
