Alexandra Quick

A series of fan fictions currently on the fourth book out of seven that is set in the Harry Potter universe, but is almost completely unrelated otherwise. It follows the story of Alexandra Quick, a young witch who much like Potter, was raised as a Muggle in the United States and much like Harry, she is whisked away to Charmbridge Academy at age eleven to learn how to control her magical talents. Unlike Harry, she has a fascination with Dark Magic and is generally ostracized by her peers for it. Worse yet someone appears to be trying to kill her...

The series is notable for being Darker and Edgier while still managing to capture the same feeling as Harry Potter, as well exploring magic beyond that the students are taught in schools. With one of the most realistic and coherent portrayals of Magical America, Alexandra Quick is a lot more than fanfiction, it's closer to the Star Wars novels set in earlier eras with less Lucas guidance.

Titles in the series are Alexandra Quick and the Thorn Circle, the Lands Below, the Deathly Regiment and the Stars Above

Tropes in this series include:

 * Animal Motifs: Alex and Thorn in particular.
 * Badass Bookworm: Alexandra
 * Black and Grey Morality: Present since the start, but it really comes to the forefront from the climax of Deathly Regiment onwards.
 * The Fair Folk
 * Fantastic Racism: Much like the stories they are based on, wizards in the AQ-universe tend to look down on Muggles, Muggle-borns, House-Elves and non-humans. They are, however, genuinely shocked, appalled and/or confused when David and Alex try to explain mundane racism and sexism to them.
 * Holy Shit Quotient: The entire series is good at this, but the Stars Above in particular seems to be fueled by unleaded HSQ.
 * Kappa: Encountering one is Alexandra's first real step into the wizarding world.
 * Our Monsters Are Different
 * All Trolls Are Different: Ours work in tollbooths.
 * Our Ghosts Are Different
 * Ravens and Crows
 * Skin Walker
 * Well-Intentioned Extremist: This is Abraham Thorn's entire shtick. Needless to say, he does not like the way things are run in the Confederacy and he does not pull his punches.
 * A Worldwide Punomenon: Trollbooths
