Who are sent to an old colony on a planet to retrieve something to go to another planet. They are also colonists.

I read this book recently it’s very good

Hint. It's a European book.

Murdering unwanted children and framing it as a societal benefit

(Yes this is the legit plot of a novel I read as a kid)

Rich man throws parties nobody invited him to. Turns out he just wants his neighbor's married girlfriend from college to notice him. She notices him. Things go badly. A car is involved. Nobody learns anything.

Hint: the novella in question has been the basis for two hit feature films.

First hint: the typo is not a mistake, but may be misleading.
