Аудгiльд Сульберг "Привиди проти суперкрутих" (Повiсть)

Anna Bea is hardly recognized anymore! The girl has become much braver since we last saw her: she now sings in a band and even dares to go on a school trip to the mountains. On this trip, both her friends and the super-cool upper-caste will experience new adventures and learn more about each other. They will have to solve the mystery of a ghost that makes eerie noises and wanders the corridors of a former abandoned hotel at night. Oh, you have never dreamed of such horrors! Meanwhile, Anne Bea unexpectedly becomes involved in a love triangle, which is also not easy to get out of.
