Forbidden Planet by Rinelle Grey

He needs a miracle.
When Captain Tyris Bekkert crash lands on a planet that’s been deleted from the star charts, he’s sure he’s doomed. What he doesn’t expect is to find a village. The residents seem strangely reluctant to help him escape. All except Marlee.
She needs a partner.
For Marlee, trapped on a dying planet, Tyris’s spaceship is a lifeline–an opportunity to change her future. She agrees to help him repair the ship, if he’ll pretend to be her partner to appease the village council, who are obsessed with securing the next generation.
As winter closes in and they’re cut off from their only means of escape, their pretence is tested to the limits, likewise Marlee’s own resolve. The handsome space captain is everything she’s always wanted. There’s only one problem.
In order to stay together, they need the one thing they can’t have—a baby.
