Рамиль Латыпов - Whistler. He’s coming for you

Viktor and Petka have been best friends since childhood and it’s not surprising that they went to summer camp. It is also not surprising that our heroes could not just spend the summer, because they are young and they have something that others do not have, boundless imagination and artifacts of the archaeologist’s grandfather. The book is mostly humorous, so don’t expect complicated mysticism from it.
