I've finished reading that.

It's very well written technically - better than Eliezer who overindulges in speechifying, hyperbole, and italics - but in general Harry doesn't seem disturbed enough, heals too easily, and there are too few repercussions from his foreknowledge. (Snape leaving and usurping Kakaroff at Durmstang seems to be about it.)

That, and the author may never finish, which is so frustrating an eventuality that I'm not sure I could recommend it to anyone.
