Everything you need to understand or teach King Zeno by Nathaniel Rich.
Set in New Orleans in the aftermath of World War One, King Zeno is the story of a traumatized detective, a young trumpet-player, and the head of a shadowy organization. Their lives come together when a series of murders shake the city. Rich's novel is both an exploration of trauma and racism and their effects on the mind and body, and an ode to the city of New Orleans. Desire for immortality clashes with duty to family in this rich and suspenseful novel.
