The reading experience

Why it stands out.

Galaxy “Alex” Stern is offered a place at Yale because she can see ghosts. Her work for Lethe requires observing the magical activities of societies whose wealthy members expect protection from consequences.

The novel combines procedural investigation with trauma and institutional critique. Its darkness score reflects persistent exploitation and horror, not merely a gloomy campus aesthetic.
