It's mostly Neville gen, rated PG-13, with hints of Neville/Ron and Harry/Hermione. It's angst in every sense of that word (oh my God the ANGST), and the characterisations are stunning.
Please, please, go read it, it's such a brilliant, evocative story. I know some of you hate Neville, but I'm serious, this is wonderful and fantastic and woe, I need a drink now after having read it. Guh. *rereads*
I had more to say in my fangirlish gibbery review. *weeps*
