Signal Black

A grounded near-future thriller about identity, records, and institutional power

About the book

Signal Black is a grounded near-future thriller about a compliance auditor investigating records that contradict her brother's disappearance. Its suspense comes from ordinary credentials, analytics, and institutional decisions rather than magical technology. The central mystery reaches a resolution while establishing the wider world of the Mara Ellison Thrillers.

Compliance auditor Mara Ellison knows her younger brother Daniel is missing. The systems around his work insist he is still there. When a precise credential pattern returns at 03:17, Mara follows the contradictions through workforce analytics, municipal infrastructure, and institutional controls. The central investigation reaches a resolution while opening the wider Mara Ellison Thrillers series.

Questions readers ask

Is Signal Black part of a series?

Yes. It begins the Mara Ellison Thrillers series, but the central investigation in this volume reaches a resolution rather than ending as an unfinished case.

The story uses plausible workforce analytics, access credentials, compliance controls, and municipal infrastructure. It does not depend on conscious or magical artificial intelligence.

Do the reader resources reveal the ending?

No. The supporting articles discuss only the premise, themes, reading fit, and opening contradictions without revealing the responsible parties, Daniel's outcome, or the resolution.
