Bonded Three Lords, She Chooses The Mad One

Sienna, a beastless outcast, is thrown into the Beast Trial Camp and accidentally bonds with three lords: wolf Garrick, tiger Bram, and eagle Corvus. Her soul tears under three top marks, to survive, she must find her fated mate and seal the bond at the altar. Bullied by Fina and Rolan, she is saved repeatedly by Garrick, called a mad beast for killing his parents, but actually poisoned and framed. She chooses him despite his self-hatred. After several crises, the truth emerges: she is the daughter of the last wolf king and the high priestess, born with purifying light. She awakens her dual bloodline, defeats Corvus and Rolan, becomes wolf king, and saves Garrick. They confirm their bond.
