Flint in the Bones by 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.

Quantum Curators and the Fabergé Egg by Eva St. John

Death or Glory – just another day in the office. When a priceless Fabergé egg comes to light everyone is after it. Neith Salah is a quantum curator. It's her mission to get the egg; she doesn’t know what it looks like, or where it is, but she knows it’s not on her earth. Julius Strathclyde lives on a parallel earth. He's a Cambridge professor and an archivist; he loves tea, research and a quiet life. It's a pity then, that he's the only person alive who knows where the egg is. She has guns and attitude, he has a fountain pen. Together they are going to have to race against time to save the egg, before a hidden enemy gets there first.
