The Squirrel Protocol (2025)
Book 1 of the Harper Quinn Mystery
What begins as a bizarre investigation quickly unravels into something far darker: a conspiracy buried deep within the justice system, a powerful family pulling invisible strings—and a past Harper deliberately erased to survive.

The Red Scarf Directive (2026)
Book 2 of The Harper Quinn Mystery
As conflicting reports surface and false confirmations spread, Harper is forced to confront the architecture beneath the investigation: systems that don’t need orders to cause harm, only permission to continue.

The Quinn Protocol (2026)
Book 3 of the Harper Quinn Mystery
When a sealed file labeled QUINN PROTOCOL resurfaces, Harper is offered a role she never consented to—one that places her outside traditional authority, tasked with judging systems that have failed too quietly to confront directly. The invitation is polite. Procedural. Careful.
