Detective Elias Rourke thought he buried his past when he closed the case that killed his partner — but when a ledger of names appears, each marked with a red triangle and ending in mysterious deaths, his own is next. As bodies surface and messages taunt him, Rourke uncovers a network of silent enforcers called The Caul Syndicate — collectors of debts written in blood and guilt.
Haunted by what he’s done and hunted by those he betrayed, Rourke must decide whether to expose the truth or erase himself completely.
In “The Ledger,” redemption and damnation are written in the same ink.

When she isn’t writing, Nicole can be found exploring coastlines, decoding vintage shortwave broadcasts, or sketching story ideas in storm-weathered notebooks.View all by nicole castellanos
