A Blade So Black by L.L. McKinney

A fresh take on an old classic, A Blade So Black is a through-the-looking-glass YA urban fantasy with a black teen heroine named Alice.
Combining the whimsy of its source material with the ass-kicking of Buffy the Vampire Slayer, A Blade So Black is a modern-day Alice in Wonderland retelling with a black teen heroine. Alice comes from a long line of warriors who battle Nightmares in the dark and terrifying dream realm known as Wonderland.

When her trainer, the handsome but enigmatic Hatta, is inflicted with “the madness,” Alice must embark on a dangerous journey—deeper into Wonderland than she has ever gone before.
