Planetfall

omg this is a gem, and I've slept on it for ten years!

Planetfall is a scifi novel about space exploration, community, betrayal, and mental illness, in no particular order. It's superbly written, and the characters are deep and complex, and the gradual unpacking of the narrative is masterful.

Close whatever you're reading this on and go read Planetfall!

A really good read, the main character is nuanced and the plot strong -- even though the trope "I have a really dark secret, let me tell you about it much later" is a bit overused in novels, it still works, as the story is more than just that.
