The name translates to Vi er ikke alene in Norwegian and We Are Not Alone - The Anthology Stories About Our Invisible Helpers in English.
The message of the book is that everyone has, from as early as birth, at least one guardian angel, who stands by the protégé's side all their life and appears only in dangerous situations.
She claims that her guardian spirit is a tall, light man called Virgil.
Vi är inte ensamma is based on letters from people whose lives guardian angels have effected.
Sandemo received thousands of such letters after requesting them in the Norsk Ukeblad (Norwegian Weekly Magazine).
