The Heart of a Secret

As the heir to a powerful Mafia empire, Apollo Villasueca's life is full of secrets-and danger. When threats against him escalate, his father assigns Ark Rosario, an elite Nemesis operative, to be his bodyguard.

Cold, disciplined, and haunted by her past, Ark sees Apollo as nothing but a mission. Her no-nonsense demeanor clashes with Apollo's lack of maturity.

But beneath his carefree façade lies a boy desperate to escape the cage of his father's world.

As enemies close in and buried truths surface, Mikasa and Apollo must rely on each other to survive. But in a world of betrayal, can they protect their hearts as well?
