Luna Kiryuu, a rare pureblood vampire, has spent years hidden away from the treacherous politics of vampire society. But when she arrives at Cross Academy, she is thrust back into a world she once abandoned a world ruled by power, secrets, and blood.
Drawn to Kaname Kuran, the pureblood prince who was once her closest companion, Luna finds herself caught between the past they shared and the dark future awaiting them. As tensions rise between humans and vampires, she must decide where her loyalty lies-by Kaname's side, or in the shadows of her own destiny.
With forbidden love, betrayal, and the weight of their immortal lineage pressing upon them, Luna and Kaname walk a dangerous path. In a world where trust is a fragile illusion and love can be a curse, will they find solace in each other, or will the crimson moon foretell their downfall?
