Ugh, cold, please go away.

ON the other hand I have gotten ahead in my reading. Does anybody have recs for a good young adult or elementary novel to pair with The Three-Body Problem? Goblin Emperor and Castle Hangnail turned out scarily well-matched so far (When the castle loses its master, the young people who were the last heirs anyone would expect must take possession; prove themselves to the courtiers and the locals; overcome histories of abuse, seriously inadequate educations, and their own natural inclinations toward kindness and mercy; and build bridges both literal and metaphorical in order to bring peace and prosperity to the surrounding lands as the courtiers struggle to find their place under the new regime.)

Anyway so now I need one to pair with "The Three-Body Problem" but I'm coming up unexpectedly blank? It's apparently about a planned alien invasion and people on Earth (mostly scientists and government) scrambling to figure out how they are going to respond.

The closest I've got in my unread YA shelves at home is "Freddy the Pig and the Baseball Team from Mars" which I suspect is not a very good equivalent, but then I have been surprised before.

Anyway I didn't expect to be this stumped but the library's catalog isn't giving me much for YA novels about alien invasions either. I guess all the dystopias lately are homegrown Earth dystopias. Any suggestions?
