IMHO, lots of themes explored or mentioned here. Deep characters, with different cadence of growths. A cool world premise, but what got me is the ecologist twist, as well as the acceptance of the weird, non-human.

I would've liked to know more about what happened on the ship, but at the same time, the fact that we don't know what happened, that we only read the lasting generational trauma, is quite eye-opening for me.

Very good read, though long in the middle, and a bit of repetitious.
