The Phantom Queen

Born into blood and shadows, Seraphina Blackthorn (often called Sera or The Phantom) is a girl stolen from her mafia-king father as an infant and raised under abuse, only to be forged into one of the deadliest assassins in the underworld. Scarred, ruthless, and feared as the Phantom of Death, she hides her broken past behind cold precision and deadly skill.

Alongside her three best friends-Aiden, Kai, and Ezra-who became her found family, Sera carves a name into the criminal underworld as a ghostly assassin leaving behind only a mask as her calling card.

But fate twists when her path collides with the Blackthorn Mafia Princes-seven brothers she doesn't remember but who have been searching for her since the night she was stolen. Chief among them is Cassian Blackthorn, the silent, fearsome heir who becomes obsessed with unmasking the Phantom and bringing her home.

Caught between the family that raised her in shadows and the bloodline that claims her by right, Sera must decide who she truly is:

the assassin forged by cruelty,

the sister long-lost to the Blackthorns,

or something more dangerous than either.

Her journey spirals into a storm of betrayals, secrets, and forbidden loyalties, where love and bloodshed blur. To survive, Sera must face her past, choose her future, and discover whether she is the Blackthorn princess... or the Phantom Queen destined to rule the underworld.
