The Do No Harm Series follows Tessa Monroe, a night-shift ER nurse whose oath to save lives becomes the weapon used to destroy her. When discharged patients begin turning up dead—and every victim is someone she treated—Tessa becomes the unwilling center of a deadly pattern rooted in a past she was never meant to remember.
Deep beneath the hospital, a forgotten network of behavioral chambers created by the infamous Mother Blackwell still hums with life. And within those walls live the remnants of her cruel experiments: children shaped into weapons, identities stripped, minds restructured. Subjects who were designed—not born.
Tessa was Subject 001, the first child Mother ever tried to break. The only one she failed to control. And the one they all want back.
As hidden subjects awaken—each more dangerous, more haunted, and more loyal to the pattern than the last—Tessa must confront the truth Mother buried: her empathy was never a weakness. It was the one variable capable of unraveling the entire system.
Across the series, Tessa fights to reclaim her stolen identity while navigating impossible alliances with those created beside her:
- Nathan Drake, the detective whose connection to her runs deeper than memory.
- Rowan, the subject who escaped but never healed.
- Elias—the Third Man, the hunter shaped from her trauma, bound to her by obsession and design.
- Subject Five and the others who emerge from the shadows, each driven by their own fractured loyalty.
As the pattern escalates, Tessa becomes both target and threat—caught in a war she did not start but may be the only one who can end.
Do No Harm is a psychological, medical, and emotional thriller series about trauma, resilience, identity, and the dangerous power of systems that believe they can shape human beings into something less—or something more—than human. The oath says do no harm. But for Tessa Monroe, survival may mean breaking that vow… before the past breaks her first.
