One possible plot could be that Nathan and Karen are abducted while Karen is pregnant. Maybe the abductors are after something related to Nathan's work or family secrets. They have to protect their unborn child while trying to escape. For example, Nathan could use his wits and some skills he has to outsmart the abductors and find a way to get help.
They could have friends like Lily and Tom. Lily might be Karen's best friend who is always there to give advice on pregnancy, like what kind of maternity clothes to buy. Tom could be Nathan's friend from work who offers to help with any DIY projects for the baby's room.

Imagine Nathan and Karen are abducted by a cult. The cult believes that Nathan and Karen are the chosen ones to lead them to a new world. But Nathan and Karen know the cult's intentions are wrong.

To write an engaging story, start with a strong opening that grabs the reader's attention. Maybe start with the abduction scene itself, with Karen screaming and Nathan trying to fight back. Then, build the relationship between Nathan and Karen. Show how their love for each other and their unborn child gives them the strength to keep going. Also, don't forget about the antagonists. Make them menacing and with clear motives for the abduction.
Another option is to think about any details you remember about the author. Maybe it was a particular writing style, or if there were any other works by the same author that you've read. Sometimes, authors cross - promote their works, so if you can figure out who wrote it, you might be able to find more of their stories, including the one with Nathan and Karen's abduction and kiss.

They manage to outwit the aliens and escape, with their love stronger than ever.
