Santino Julian Mendoza has always believed in the supernatural: the existence of diwatas, duwendes, malignos, and the divine beings who have ruled the Pearl of the Orient Seas. Isla Adlawan has her own share of divine secrets that she intends to keep hidden until her dying breath. And yet... she knows that it is only a matter of time before Santino finds out about it. A brutal murder and a city-wide siege will compel the two to delve deeper into the web of lies and revelations that they will find themselves entangled with as they go on a journey to save the city of Manila from the forces of evil that lurks within its corner while preventing the greater evil that intends to rule the islands from regaining his power. Will they be able to save what matters most in the end?
