Imagine that some people have the power to affect your thoughts and feelings when you read, or they read a book to you. They can seduce you with amazing stories, conjure up vividly imagined worlds, but also manipulate you into thinking exactly what they want you to.

When Luca Campelli dies a sudden and violent death, his son Jon inherits his second-hand bookshop, Libri di Luca, in Copenhagen. Jon has not seen his father for twenty years since the mysterious death of his mother. When Luca's death is followed by an arson attempt on the shop, Jon is forced to explore his family's past.

Unbeknown to Jon, the bookshop has for years been hiding a remarkable secret. It is the meeting place of a society of booklovers and readers, who have maintained a tradition of immense power passed down from the days of the great library of ancient Alexandria. Now someone is trying to destroy them, and Jon finds himself in a fight for his life and those of his new friends.
