These Shattered Spires (Wyrdos, Bk. 1)

In this YA high fantasy, four magical rivals must work together to survive a deadly competition. Perfect for fans of Leigh Bardugo and Gideon the Ninth.

Entombed beneath a tooth-filled sky, the world rots. At the heart of the decaying world is Fourspires Castle, home to arcanists from the four disciplines--bone, blood, botany, and stone.

The castle is thrown into chaos when the ruler of Fourspires is assassinated. To crown a new ruler, the arcanists and their human familiars must kill or be killed in a bloody fight to the top of the Fifth Tower. For the familiars, who are the arcanists' servants and sources of power, this will mean certain death.

Amid the bloodshed, four rival familiars must work together . . . Taro, a bone witch still obsessed with her ex. Nixie, a botanical familiar determined to do anything for her freedom. Elliot, a cursed and vengeful blood familiar. And Alix, a banished stone familiar shrouded in secrets.

It's a dangerous and deeply illegal quest, but if they want to survive, the four must ally long enough to battle reanimated skeletons, possessed plants, and undead nuns . . . if they don't kill each other first.
