The guardians of the castle. Underwater adventure

Join Víctor, Lara, Sofía and Martín as they embark on their most thrilling expedition yet in Los Guardianes del Castillo. Aventura Submarina. When a mysterious castle appears in the park, the four courageous children don their explorer’s hats and dive into an underwater realm full of surprises. With vibrant illustrations and playful design, this book invites early-readers to engage not only by reading the story but by participating: solving puzzles, facing small challenges and unlocking hidden clues along the way.
Published by Ediciones Llum de Lluna and written in uppercase letters for beginner readers, the layout ensures readability and boosts confidence in people just starting to read independently. The story mixes adventure and imagination: what starts as an ordinary day in the park leads to an incredible descent beneath the waves, where the castle hides secrets, games, and magical discoveries. Children are encouraged to think, explore and participate.
