Arthur has always believed he was born weak.

A frail body, a neglectful family, and a lifetime of isolation have taught him that survival means staying quiet, invisible, and alone. But when a mysterious invitation arrives-an invitation written in blood-his miserable life begins to unravel.

One by one, families connected to the invitation disappear. A beautiful, terrifying woman lurks in the shadows. And Arthur finds himself drawn into a nightmare alongside two classmates: Mario, a cold genius hiding dangerous secrets, and Emily, a girl haunted by silence and fear. What begins as a strange mystery quickly becomes a descent into betrayal, captivity, and a gathering known only as the Blood Party.

Forced to drink blood that awakens buried memories, Arthur discovers a truth more horrifying than death itself: his life was stolen from him long ago. His weakness was taught. His memories were erased. His parents were murdered. And the monster he fears may be the only one who remembers who he truly is.

As past and present collide, Arthur must confront a question more terrifying than vampires or death: If your entire life was a lie, what kind of strength does it take to reclaim it?
