The Last King of Shambhala by Daniel Grant Newton

A man is discovered close to death in the Himalaya Mountains by two Nepalese herders, and adopted into their family. Suffering amnesia, he is given a book that will reveal his identity. The book contains three very different stories involving the Nordic gods, psychic spies in World War Two, and a teenage boy experiencing a fantastical alternate reality during blackouts at school – all somehow piecing together and revealing the mystery of the amnesic man's identity. Embark on a new kind of journey of myth, fantasy, love and... well, peculiarity.
