A propulsive suspense novel about a risk analyst racing to dismantle a revenge engine before it detonates her family and an entire city.
In seven days, the Veil Protocol will go live. After a decade modeling chain reactions for Harbor & Pike in Boston, Mara Ellison trusts numbers more than people. Then a black envelope arrives on her desk containing a silk mourning veil, a disposable phone, and a message: "Count your debts." An anonymous architect has built a decision tree of real-world triggers that will culminate in a catastrophic data dump implicating her father, the revered head of Ellison Therapeutics in Providence. Each sunrise brings another "nudge"—an elevator stall in the Prudential Center, a misrouted EMS call in Allston, a timed blackout during WaterFire on the Woonasquatucket—small incidents that spool panic into policy failures.
Mara's list of suspects is painfully intimate: Gavin Roe, her cybersecurity-expert ex who knows her passwords and blind spots; her estranged sister Lena, freshly returned from an activist collective in Pawtucket; and Dr. Francine Holt, the Tufts advisor who taught Mara to map consequences like constellations. With only her cranky neighbor Theo Parr—a disgraced investigative podcaster with a police scanner and a battered Saab 900—Mara builds a war room of corkboard and red twine, chasing clues from the Longfellow Bridge to a shuttered mill off Broad Street in Central Falls.
Behind a false wall, the Veil hums: a rack of servers, a live dashboard, a countdown at 00:07:19. Every choice Mara makes rebalances the tree—and costs someone else. As alarms scream and the river fog thickens, she realizes the architect learned the math of guilt at her own kitchen table. To stop the final cascade, Mara must uncover the one debt her family buried, and decide which consequence she can live with.
