La madreperla mágica (La biblioteca rosa. Mermaid Magic, 3)

In the magical underwater kingdom of Sirentropia, the energy source that keeps the mermaids alive is about to run out. Merlinda, the king's daughter, is determined to find Neptune's pearls that can save her home, even if it means facing sea monsters, ancient ruined palaces, and a skeleton pirate who dreams of conquering the oceans. Luckily, she's not alone: ​​her mermaid friends Nerissa and Sasha, and her human allies Tyler and Celia are always by her side. Things get complicated when a whale gets caught in a fishing net, a giant octopus appears guarding the pearls, and a sinister sea witch decides to lend her magic to the terrible Redbeard. Between surprising rescues, new water powers, tentacles everywhere, unruly seaweed, and a mermaid dog capable of finding treasure, the group will have to use their wits, courage, and a good sense of humor to avoid getting themselves tangled up in the chaos. The adventure blends action, humor, and tense moments, with some emotional scenes that make it clear that these mermaids are much more than just sparkly tails.
