Flint in the Bones (Norwich Map Runners Series #1) - Eva St. John

In a city where history bites back, murder is just the beginning.

Detective Eliza “Bish” Barnaby thought she’d left her home behind—along with its plague outbreaks, random time-shifts, and tendency to accidentally host people from the 1600s during breakfast.

But when a dangerous practitioner escapes custody in London, Bish is forced back to Norwich, a city where ancient maps hide deadly shortcuts, angry nuns have scores to settle, and Puritans throw acid at those they don’t approve of.

Armed with only a gun she can’t fire, a spaniel who thinks he’s a wolf, and a partner who dresses like a rejected Bridgerton extra, Bish must stop a killer before wild magic unravels the city’s fragile balance.

But keeping her own forbidden talents hidden is just as dangerous as catching the murderer. And in a place where past and present bleed together, the only way to solve this mystery might be to embrace the very magic she fears.
