Maren has spent thirty years trusting one thing above all else: her own judgment. Now ships are vanishing across the Shattersea, the Office has named a familiar siren threat, and the evidence refuses to fit the story.
A gap in Maren's own field record says something happened aboard the Black Wake that neither she nor Sable can remember choosing. As survivor accounts contradict wreckage and official conclusions harden into fact, Maren begins to suspect the danger is not one monster, but a pattern someone has built on purpose.
Following the truth means leaning on Sable, the bonded partner who has spent twelve years knowing Maren better than anyone alive. Their carefully controlled intimacy is already becoming something neither of them can file away. It also means trusting Ellis, a quiet courier whose interest in Maren feels dangerously personal and whose answers are too precise to be accidental.
If Maren is compromised, trusting herself could get people killed. If she is not, surrendering her judgment may be exactly what someone is counting on. False Depth concludes the Shattersea duology and should be read after Black Wake.
