Who has poisoned the king? Phyllis is allowed to live as long as she writes down everything she knows about Alexander. She tells a brutal story of the violent daily life in the war, about the planning of the expansion into the Arabian Peninsula, about an invisible library containing marvelous manuscripts and discoveries, and about the passion between a cook and a king.

With The Invisble Library, Thorvald Steen interweaves known and unknown, relying on facts until they run out, then building his story on what is probable, to tell the story of a little-known period in the life of one of the most renowned figures in history. The result is an existential and inspired novel that goes to the heart of the human experience--who are we in war, in love, during the final days of life?
