I’m really hoping someone can help me with this one because I’ve been trying to remember the title for years now after losing the book in a move.

It is a romance I read in the late 90s set in the Midwest while building the railroad. The woman gets hired on with the train company and makes pies in the dining car (I think shes running from an arranged marriage or bad home situation like dean guardian?). Her big thing is pie making, lots and lots of pies. Eventually the company moves up into the mountains (?) where she is responsible for cooking for the one crew. She gets involved with the lead foreman (?) and at some point gets kidnapped by an Native, and he goes after her. Pretty sure I remember her being pregnant when shes kidnapped. And that’s about the sum total of my memory on this one. Thanks!
