In the stunning conclusion to the Dear Reader trilogy, discovering the truth about Ashwood was only the beginning. Now, Clara Ashwood must confront the most shocking secret of all—her own.

The release of The Ashwood Confessions has shattered the town's facade, but the fight for justice is far from over. While local conspirator Nathaniel Reed faces his reckoning, the true architect, State Senator Richard Harrow, remains shielded by influence, and the federal investigation mysteriously stalls. As Clara grapples with the compromised system and the lingering threat from Harrow's network, a posthumous package from a fallen ally reveals a truth hidden even deeper than Ashwood's crimes: Rose Ashwood gave up another daughter years before Clara was born.

Seeking out her unknown half-sister, Nora Sullivan—a skilled book conservator living a quiet life in Vermont—Clara is pulled into the earliest, most foundational secrets of the network that entangled their mother. Together, the sisters must decipher Rose's final, most intricate puzzle—"The Binding Thread"—a cache of evidence powerful enough to bypass political obstruction and expose Harrow himself.

But the network is closing in. With Eliza Grey captured and used as leverage, and compromised agents monitoring their every move, Clara and Nora must race against time, navigating hidden archives, deadly confrontations, and the chilling ideology behind the "collected" women. To fulfill her mother's legacy and reclaim her own story, Clara must embrace her role not just as Reader, but as Author, ready to write the final, dangerous chapter, whatever the cost.
