The girl Eliza loved the sea more than anything in the world. More precisely, the sea was in second place, and in first place was her grandmother Maura’s house on the seashore and her grandmother herself. Eliza also loved the letters that her grandmother sent her. And when, in her next letter, Mora invited her to visit, because the time had come for a special adventure, Eliza immediately set off. Silver Glare was the princess of the ocean, its formidable legend and protector. And she had no intention of leaving her native abyss. Until one day I saw the light of a special star. What connects them - a girl and a mermaid infinitely far from each other? A mystery, covered in fog and splashing waves, a story about magic, courage and, of course, love. An adventure awaits Eliza. Silver Blik too. And maybe in the end the old mystery of the mermaid with night-black hair and a shining star will finally be revealed.
