The Priory of the Orange Tree (The Roots of Chaos, #1)

by Samantha Shannon

Kalyba let out a soul-wrenching cry, and her body contorted. Every auburn tress was cooked from her scalp. Flesh melted from her limbs and cooled again into pale lines. Black hair rushed and rippled to her waist. Aghast, Ead forced her hands to close. When the flames dwindled, Margret was on all fours, one hand at her throat, eyes bloodshot. And Sabran Berethnet was standing beside her. Ead stared at her palms, then back at Kalyba, who was also Sabran. Margret pushed herself away. “Sabran?” she coughed out.

Kalyba first queen of inys!?!? This is 1000% one of the craziest twists in the book
