This new rendition of the classic Faustian bargain has a brilliant conception and is an enjoyable read, but lacking in resolution and more importantly information. I find it somewhat impressive that they manage to actually make you care about these kids (excepting Victoria who never had my sympathy past the prologue), despite how horrid they are. I was pleased that B. manages to resist Madame Villeroy, and is able to assist the others, but apart from the bits at the beginning of the chapters, we know precious little about Villeroy herself. Enough, certainly, to know what she is, but more background and motivation on her part would have enhanced the story for me, as well as deeper characterization of the kids. I suppose in some ways I was expecting something with more substance, so while I still like the book, especially the idea, it just did not strike me. I will however be looking out for more books by this brother and sister writing team....
