Opio en las nubes is a surreal and dreamlike novel by Rafael Chaparro Madiedo. The story is narrated by Pink Tomate, a peculiar character who is both a cat and a tomato. Pink Tomate offers a whimsical and reflective viewpoint on life, often pondering whether he is more of a cat that likes tomatoes or a tomato with the face of a cat.

He enjoys the scent of vodka mixed with flowers, particularly in the mornings when his owner, Amarilla, returns from a night filled with parties, sweat, and smoke. Pink Tomate admires Amarilla's vibrant lifestyle, though he sometimes feels exasperated by her relentless energy and the sadness she carries.

Amarilla often sings melancholy songs, like I want a trip trip trip, to cope with her mornings or perhaps to embrace the chaos of her life. Pink Tomate's narrative is filled with existential musings and colorful descriptions of his surroundings, making Opio en las nubes a unique exploration of identity and reality.
