Al filo de la oscuridad (Tapa blanda con solapas)

The blend of intense supernatural elements with passionate love stories creates a unique tone. I'm curious how much of that was planned from the start or evolved during writing.

The stories carry a heavy dark tone but also moments of tenderness. How did the author balance these contrasting emotions to keep the reader hooked?

The variety of supernatural elements felt rich and diverse. I wonder if the author drew from personal interests or mythologies while crafting these worlds.
