Hellfire and Handbaskets — Kathryn Hills

It's hell in the ER, but Army veteran Dr. Rick Hauser wouldn't work anywhere else. The hardened combat medic thinks he's seen it all. Until she storms into his life. Amelia Pennington is not just a pretty face. She's a time-traveler. A medical student from 1895, forced to flee a madman. She's been in trouble before, but this time everything she loves is at risk. Can a reluctant hero be the key she's searching for? What's left of Hauser's heart is still on the battlefield. Last thing he needs is to get tangled up with a mystery woman. But when he finds Amelia on the streets, he ignores the warning shots firing off in his head and takes her home. In less than twenty-four hours, she's upended his self-protected world. Even his dog, Rocky, is in love.
