Molly and Jack go to the small island of Ravenstorm to visit their aunt and uncle. According to legend, an ancient curse hangs 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 images of ravens and asks them never to take them off. There are also stone statues of children everywhere on the island and some pretty creepy caves. Strange! And then, during one of his walks, Jack... disappeared. However, Molly's aunt and uncle tell her that Jack doesn't exist! It's like they forgot about him! Molly is ready to do anything to find her brother. But she never could have thought that elves and underground spirits were involved in the matter. And these are definitely not the kind little creatures from children's fairy tales...
