Fertile Betrayal by Becky Bohan

In a rural Minnesota town, veterinarian Nedra Wells tries to get to the bottom of the fertility problems of the cows on a struggling farm.

----
Veterinarian Nedra Wells has moved to a small town in Minnesota
to open her own mixed-animal practice. For years she has
envisioned being a country vet like her father, and after meeting
and falling in love with school teacher Annie Callahan, Nedra was
sure she could have it all--the career, the lover and life in a
small town. It's what she's always wanted. It should be perfect.
But it's not. Nedra and Annie's reception in town--as low-
profile, but unmistakable lesbians, has been polite, but cool.
Annie's reservations about leaving their urban life have not been
replaced by a happy settling in. Her sense of isolation seems
only to increase with her fear that sharing a life with Nedra
will mean giving up her own. Against a backdrop of a possible
fracture in her relationship, Nedra's practice confronts her with
a deadly health crisis in a local cattle herd. Baffled at first
by her inability to diagnose and treat the problem medically,
Nedra's inquiry leads her into a broader investigation and
ultimately, to the solution of a very human problem.
