Inspired by a real environmental disaster, this book follows the advance of an oil spill as it spreads across the sea, transforming landscapes and affecting the animals in its path. Through poetic language and a carefully paced narrative, Guilherme Gontijo Flores invites readers to witness the growing impact of an ecological threat that becomes impossible to ignore.

Daniel Kondo’s illustrations play a central role in the storytelling. Working with a restrained palette, the artwork visually recreates the stain’s expansion across the pages, creating a powerful dialogue between text and image and immersing readers in the unfolding events.

Rather than offering direct explanations, the book encourages observation, reflection, and discussion. Its combination of literary quality, visual sophistication, and environmental relevance makes it a compelling picture book for contemporary catalogs, addressing a global issue through an accessible and emotionally engaging reading experience.
