Casino Infernale

When the supernatural underworld needs financing, it turns to the Shadow Bank — and once a year, the Shadow Bank hosts Casino Infernale, where the currency is souls and losing means something far worse than bankruptcy. Eddie Drood and Molly Metcalf go in with a mission to bring the whole operation crashing down, but between the rigged tables, the monstrous clientele, and the very real possibility of losing everything that makes them who they are, survival starts to feel like the optimistic outcome. Green keeps the stakes visceral and personal, grounding the world-ending consequences in a relationship readers have watched develop across seven books.

What makes this entry in the Secret Histories series particularly satisfying is Green's confidence with his own mythology. By this point in the series, he writes Eddie and Molly with genuine warmth and wit, letting the banter carry real emotional weight rather than just charm. The casino setting gives the narrative a tight, propulsive structure — each game a ratcheting of tension — while Green's gleefully overstuffed imagination ensures the pages never feel formulaic. It reads fast, but there's craft underneath the momentum.
