What a phenomenal conclusion to a phenomenal series. The crew of the Unstoppable is back, and after the conclusion of the last book, they know they have to find solution to the bereavement before all life in the universe is destroyed. But they're also on the run from the Royal Compassion and the Firmament .

There are so many themes I love in this book: friendship, holding onto your ideals in conflict, and justice.

I loved all the narrators on the audiobook and how they give voice to each character.

Thanks to Netgalley and the publisher for an ARC in exchange for an honest review.
