All of Us Villains (All of Us Villains, 1) by Amanda Foody and C. L. Herman. 2021. Hardcover (YA)

You Fell in Love with the Victors of the Hunger Games.
Now Prepare to Meet the Villains of the Blood Veil.

The Blood Moon rises. The Blood Veil falls. The Tournament begins.

Every generation, at the coming of the Blood Moon, seven families in the remote city of Ilvernath each name a champion to compete in a tournament to the death.

The prize? Exclusive control over a secret wellspring of high magick, the most powerful resource in the world―one thought long depleted.

But this year a scandalous tell-all book has exposed the tournament and thrust the seven new champions into the worldwide spotlight. The book also granted them valuable information previous champions never had―insight into the other families’ strategies, secrets, and weaknesses. And most important, it gave them a choice: accept their fate or rewrite their legacy.

Either way, this is a story that must be penned in blood.
