City Shifter Mysteries

Meet Detective Kat Kale

IIn a city where humans, shifters, and hybrids coexist in a fragile truce, Detective Kat Kale walks the razor’s edge of the law—solving murders, chasing down killers, and annoying just about everyone along the way.

As part of the newly formed Hybrid Squad, Kat is thrust into cases no one else wants—high-risk, high-body-count crimes that threaten to tip the city into chaos. With tensions rising between species, corruption lurking in the shadows, and enemies on all sides, every case is a fight for justice… and survival.

But when the hunters become the hunted, and the lines between predator and prey blur, Kat must decide how far she’s willing to go to protect the city—and whether she can survive long enough to do it.

Murder, secrets, and a city on the brink. Welcome to the City Shifter Mysteries—where justice is never simple, and danger is always one step behind.
