SOLVED. Half dragon shifter ran from intended cause half's can be thrown like yesterday's garbage if barren

[Myst]

I think the book was a crossover book.
The girl is a kick-ass firefighter who ran from her future intended cause if it turns out she's barren (can't have kids) the male can throw her away & look for a new wife. She didn't want to chance it so she ran. Cue strange fire & her intended who's looks into how the fire started. Fellow in her team liked her a whole lot & he went on to a new town to get away in another book. A family member was the person who died who was also a half who gotten thrown out.

Turned out (view spoiler)[ it was some bigwig dragon council member that was killing the women. Purity & all that jazz if I remember right. (hide spoiler)]

I want to say the book was last year & the other was this year. (I'm looking for book 1)
