Vampire plutocrat House Abraham dominates the Secret Covenant. The old prince names granddaughter Adele, of rare heterochromatic blood, successor over his son. The coronation is a death trap: uncle August allies with rival House Gustav and werewolves, poisoning Adele to seal her Blood Domain. Alone and dying, she escapes. Ambushed by Victor, she is saved by vengeance-bent werewolf chieftain Fenrir in black wolf form.
