My fiancé read a book when he was younger, but he cannot remember the title or author.
The human race colonized another planet and decided to abandon the colony for one reason or another.
The older people, who had spent their whole life on the colony decided to stay behind, and the book was about how the native life of the planet started coming back to life after most of the humans left.
I have no idea, it sounds like nothing I can think of. He says he thinks it may be a female author.
Can anyone help? Thank you!!!!
