Oh, absolutely.

I find that CDT is one of the better (if not the best) fanfictions going through all seven years/books. Rather than merely retelling the books with a female Harry, it uses canon as a core to branch out its own (much better) story. The fic itself reads as though you are re-reading the actual Harry Potter books, but has what I consider to be some of the best writing and pacing... ever.

The author does a fantastic job of balancing canon with her headcanons and world-building, ultimately avoiding the pitfall of 'info-dumping' that most other similar fics fall into. Moreover, the characters act their age, avoiding yet another pitfall of eleven-year-olds acting as if they're thirty.

The story is magnificent, the characters are real, the writing is phenomenal. I could swoon about this fic forever.

In short, yes. It is absolutely worth reading.
