Off with their heads / Zoe Hana Mikuta.

Enhanced descriptions from Syndetics:

Fans of Chloe Gong and Judy I. Lin will devour this Korean-inspired Alice in Wonderland retelling about two very wicked girls, forever bonded by blood and betrayal . . .

In a world where Saints are monsters and Wonderland is the dark forest where they lurk, it's been five years since young witches and lovers Caro Rabbit and Iccadora Alice Sickle were both sentenced to that forest for a crime they didn't commit-and four years since they shattered one another's hearts, each willing to sacrifice the other for a chance at freedom.

Now, Caro is a successful royal Saint-harvester, living the high life in the glittering capital and pretending not to know of the twisted monster experiments that her beloved Red Queen hides deep in the bowels of the palace. But for Icca, the memory of Caro's betrayal has hardened her from timid girl to ruthless hunter. A hunter who will stop at nothing to exact her vengeance- On Caro. On the queen. On the throne itself.

But there's a secret about the Saints the Queen's been guarding, and a volatile magic at play even more dangerous to Icca and Caro than they are to each other...

Lush, terrifying, and uncanny, Zoe Hana Mikuta-author of Gearbreakers and Godslayers -takes a delicate knife straight through the heart of this beloved surrealist fairytale.
