Aliena

Aliena is a nice person who turns out to be an alien in a human host. She just has things to learn about the human form and society. When her body starts immune-rejecting the alien brain, and the brain has to be replaced by another alien brain, maintaining the semblance of marriage and family becomes a challenge for both Aliena and the man who loves her.

Lida Fisher knows that her beloved husband, Quincy, will die soon as the result of a rare and terrible brain rejection syndrome. But there is one hope. If Quincy consents to switch brains with one of the alien beings that have arrived from the other side of the galaxy, he will live on - albeit in the body of a starfish. And that means Lida must agree to let a new man into her life and her bed, one with the face and body of her adored husband but with the mind of an alien stranger.
