Spirit Dances by C. E. Murphy

Some days, it’s not the magic that turns shaman Joanne Walker’s life upside-down.

When her day job as a police detective goes sideways, picking up the pieces means down time, inner turmoil, and—naturally—an accidental date with her boss, Captain Michael Morrison. Who is in no way a source of that inner turmoil. Obviously.
But the dance concert they’re attending—billed as transformative—turns out to be a little too literal as Joanne’s untapped shamanic ability to shapeshift is triggered. Only Morrison’s grounding presence gets her through it…and Joanne is barely under control when a murder takes place on stage right in front of them.
It’s much easier to solve a mystical mystery way outside of her jurisdiction than it is to navigate an increasingly-fraught love life, especially when Morrison, caught in a surge of shamanic power, is drawn deep into a series of murders plaguing Seattle’s homeless population. Joanne, racing against the clock to save her boss, is faced with a hard truth: she would do anything for Morrison.

Anything but give up the path she’s on.
