The Unspoken

When divers begin dying aboard a century-old shipwreck resting at the bottom of Lake Michigan, the deaths look inexplicable — and the rumors surrounding the vessel's cursed cargo make them even harder to dismiss. Paranormal investigator Katya Sokolov is brought in to untangle a mystery that reaches back to ancient Egypt, where a sorcerer's stolen sarcophagus may have sealed the fate of everyone who went down with the ship in 1898. Graham builds genuine dread from the collision of history, the supernatural, and the very modern desperation of people trying to keep the truth buried. The stakes feel personal before long, and that emotional pull is what keeps the pages turning.

Graham's gift here is atmospheric layering — she makes the darkness of deep water feel as claustrophobic and threatening as any haunted house, while keeping the procedural elements grounded enough to satisfy readers who want logic alongside the uncanny. The Krewe of Hunters series has always excelled at blending the rational and the paranormal without letting either undercut the other, and this installment finds that balance with particular confidence. It's the kind of mystery that leaves a chill that lingers.
