Dalia Ravenstone and the Vicious Circle - Ravenstone Family series, #1

It is the first year of magic school for Dalia Ravenstone and her friends, and they're looking forward to a normal, fun learning experience full of magic and wonder at Fae Springs. What they weren't looking for was intense and bigoted bullying, a dangerous mystery, malfunctioning magical powers, and the possibility of Dalia's non-human friends being expelled from the school forever! Can they figure out who the culprit is and stop them before their group is split apart by the school board? If they do crack the mystery, can they survive the culprit's mysterious attacks long enough to call for backup? And even if they survive all that unscathed, is this just the beginning of a much more sinister plot?

The Ravenstone Family series: It's a little like the Addams Family, a little like Harry Potter (without the bigotry) or The Worst Witch, a little like the October Daye series by Seanan McGuire, and a little like none of those things. It features an ethnically and neurologically diverse cast; the protagonist of the first book, Dalia Ravenstone, is a black, autistic, transgender goth girl with chronic anxiety, chronic depression, and a missing foot (by birth). Dalia's best friends are a Korean-American boy with ADHD who uses a wheelchair, a white ginger girl who likes both girly things and tinkering with machines, a kitsune living in poverty, a Goblin foreign exchange student, and a laptop computer that acts like it's sentient.
