This book is a wish for a kinder future. It's optimistic while still being firmly rooted in realism.

Sawyer's story arc and death, while upsetting, was realistic. It was a great catalyst for the changes made to the way that the fleet treats the returning descendants of former residents. I'm glad that we got to see more of Sunny and Eyas as friends beyond their work. Tessa being able to create a home in which her family feels safe and Isabel training Kip to continue the living memory of the fleet feel like a perfect way to round off the book.

one of the things that I love the most about these books is that our heroes aren't fighting to save the universe. They're not struggling against a catastrophic war. And in the rare cases they're escaping apocalypse/catastrophe, what we see isn't statistical odds and the military. We see people surviving and thriving.
