Summary: 
Seventh grader Alexandra Quick returns to Charmbridge Academy. This year she faces bullies from another wizarding school, a secret Dark Arts club, and the machinations of her father, but her greatest trial yet awaits her in the dangerous Lands Below.
This is the second book in the Alexandra Quick series.
This story is really amazing so far. The plot is well structured, complex, and full of unexpected twists. The characters are also well developed, and I have really come to care about them. I particularly like the dynamic between Alexandra and her brother. I was really sad when I read this chapter, and I can't believe Max is dead. You're a great writer and I hope you continue.
