Red and Green Dragons

[fin3apple]

I read this book about 14 years ago. It was about a world where there were red and green dragons, except all the green dragons were extinct except for one. The story was about two best friend dragons (a girl red dragon and the one green dragon who was a boy). I think the girl red dragon's dad was king of the red dragons? And he banished the green dragon maybe because they fell in love? I am uncertain.

So the green dragon left to go see if there were other green dragons and I think the girl red dragon went with him.

I DISTINCTLY remember the cover, which had a red dragon and a green dragon flying on it.

Any help finding this book would be so appreciated!

Science fiction YA (90s or earlier) with girl protagonist

Okay, unfortunately I have VERY little information to give on this one, but who knows, maybe someone remembers the same scene from the book that I do?

It's science fiction and YA and I read it as a kid/young teen, so it must be from the early 90s or even earlier. I know the protagonist was a girl and I think she was on some space station or spaceship with her family. There was an alien threat(?) that either took over people's bodies or duplicated them, if I'm not mistaken they had red eyes when compromised and I remember that her father was one of the victims/duplicates and confronts her at some point, which I found super creepy. I don't remember anything else about the plot or cover image and I'm not sure where the book originates from but if I had to choose I'd say either UK or Germany.

I'm happy about any suggestions (if I read summaries on Goodreads or elsewhere it might bring back the memory...) Thank you ♥
