She didn’t want to leave her home, but with choice taken away from her she agrees to be an alien’s bride... with conditions.

Mila was living a quiet life. Too old to join the Volunteer program, she was resigned to her position in the middle of nowhere.
When a recruiter comes to her and orders her to join she says no. When he explains that due to her genetic heritage she has no choice, she reluctantly enters a pact to gain an education in return for her genes.
As her assigned Familiar isn’t interested in her, Mila is left on an alien world looking for someone to take on her training. Who could possibly want to take her on, body, mind and soul?
