Ninth House
Yale secret societies replace a neon-lit supernatural metropolis.
Alex Stern is the least likely person to end up at Yale: a dropout with a criminal record and the ability to see ghosts. She gets recruited into Lethe, the ninth secret society, tasked with monitoring the other eight as they perform rituals using real magic. Leigh Bardugo sets her murder mystery inside an institution built on old money and older power, creating the same layered city-over-ancient-magic feel that Maas builds in Lunathion.
Alex is pricklier than Bryce, more damaged and less willing to charm her way through situations, but both heroines use their outsider status to see what insiders overlook. Bardugo writes Yale's architecture and culture with the same specificity Maas brings to Crescent City's neighborhoods, making the setting function as a character. The mystery structure drives the plot forward with real urgency, and Bardugo drops clues that reward attentive readers without making the solution obvious.
The supernatural elements are grounded in historical occult tradition, giving the magic a weight that feels researched rather than invented. The supporting cast includes morally ambiguous allies whose true loyalties remain unclear. For HOEAB readers who want a murder mystery set in an institution hiding supernatural secrets, Ninth House is the sharpest match on this list.
