Honestly, there was nothing I didn't love about this book. The entire premise was such a knowing and intentional reworking of exactly what you think it is. I can see how it might be off putting if you weren't expecting the novel to be quite so honest about the whole thing, but that's exactly what I loved about it. There are illusions here. The story embraces its inspiration from start to finish, but changes it and evolves in new directions until it's something entirely of its own. And I loved it. I sincerely loved the entire thing. The sheer amount of FUN behind this whole story is such a shining reflection of the fanfiction experience as a whole - to love and change and relive something with so much passion that you rewrite it in different directions with different outcomes and end up with an absolute gem of a story that readers can enjoy entirely on its own merits. I don't think I've ever purely ENJOYED a novel so much in as long as I can remember.
