My Stepbrother is the Wolf King

Bella moves into the Blake family after her mother remarries, forced to share a roof with her untouchable stepbrother Arthur—cold school heartthrob by day, possessive wolf-king heir by night. She is his fated mate, and her presence awakens his wolf mark. As she tries to escape his control amid bullies and family judgment, Arthur reveals his true form at prom, marks her as his fiancée, and the two face the world together.
