When night descends, el Carnaval de Bestias rises.

Within the shores of Isla Bestia, guests from around the world discover a utopia of ever-changing performances, sumptuous feasts, and beautiful monsters. Many enter, but few ever leave — the wine is simply too sweet, the music too fine, and the revelry endless.

Sofía, a freedwoman from a nearby colonised island, cares little for this revelry. Born an enslaved mestiza on a tobacco plantation, she has neither wealth nor title, only a scholarly pragmatism and a hunger for answers. She travels to el Carnaval de Bestias in search of her twin brother, who disappeared five years ago.

There's a world of wonder waiting for her on the shores of this legendary island, one wherein conquerors profit from Sofía's ancestral lands and her people's labour. But surrounded by her former enslavers, she finds something familiar in the performances — whispers of the island's native tongue, music and stories from her Taike'ri ancestors...a culture long hidden in the shadows, thrust into the light.

As the nights pass, her mind begins unraveling, drowning in the unnatural, almost sentient thrall of Carnaval. And the sense that someone is watching her grows. To find her brother and break free, Sofía must peel back the glamourous curtain and face those behind Carnaval, before she too loses herself to the island...
