Read City Shifter Mysteries

In a city where predators wear human faces, one detective hunts the truth.

Welcome to a world where humans, shifters, and hybrids coexist in a fragile, uneasy peace—and where every crime threatens to tear that balance apart.

Cougar shifter Detective Kat Kale is one of the few willing to stand between order and chaos. Sharp-tongued, relentless, and guided by deadly instincts, she leads supernatural crime investigations that most officers won’t touch.

Each case drags her deeper into a dangerous underworld of:

  • ruthless pack politics
  • hidden supernatural societies
  • deadly conspiracies
  • and killers who know how to stay in the shadows

Worse, she’s forced to work with her longtime rival—human detective Rafe Anhelm—a man she doesn’t trust, but can’t ignore. Their partnership is as volatile as the city they protect… and just as dangerous.

As tensions rise between humans and shifters, every investigation becomes a race against time. Because one wrong move could ignite a war.

Perfect for fans of:

  • urban fantasy detective series
  • shifter murder mysteries
  • paranormal police procedurals
  • female-led supernatural thrillers
  • rival partners and slow-burn tension

Start with Feline Protector and dive into a gripping urban fantasy mystery series packed with action, intrigue, and razor-sharp claws.

In her city, secrets have claws.
