It's a crossover with Harry Potter- yes. But it barely fits canon- most of the focus seems to be on Severus Snape/Hermione Granger pairing- with the both of them, especially Hermione, re-written to fit the pairing. Really badly- Hermione is reduced to a mess because Sarah has Snape's attention and she doesn't. If you like SSHG, it's a good fic. If not, you're not missing anything in terms of the Labyrinth fic.
