Mysterious estate (#1). Gillian Philip

Molly and Jack go to the small island of Raivenstorm to visit an uncle and aunt. According to legend, an ancient curse gravitates over the castle. Brother and sister, of course, are sure that these are just horror stories for kids. But the unsociable butler gives the guys amulets with the image of ravens and asks to never shoot. And on the island there are stone statues of children everywhere and there are rather terrible caves. Strange! And during one of the walks, Jack... disappeared. However, Aunt and Uncle declare Molly that no jack exists! They seemed to forget about him! Molly is ready for anything to find a brother. But she could not think that the elves and underground perfumes were involved in the case. And these are definitely not kind small creatures from children's fairy tales...
