Koli and his companions finally arrive at the source of the signal they have been searching for, and in no way are they prepared for what they find. Sailing through the fog and coming upon what initially appears to be a giant metal wall in the water turns out to be a carrier ship larger than anything they could imagine. This ship, Sword of Albion, is a giant warship, yet it is inhabited by only a few people, and they are strange indeed. Lorraine and Paul Banner, who both appear to be friendly, and their son Stanley, who appears to be quite mean and very erratic. Paul is clearly a military man who expects to run an orderly ship and Lorraine appears to be a loving Mom doing her best to prevent her mischievous son from getting into hot water with his antics, yet it is obvious to Koli that something is not right with the lot of them. Lorraine is are also very interested in having Ursala upgrade her medical diagnostic unit so she can treat Stanley and correct some kind of genetic problem. Not sure if they are guests or prisoners, Koli and crew need to sort out the truth of the situation, or die trying...

This book adds a third PoV character to the mix, this time it's Monono, the AI girl who has elevated herself to being a full fledged member of Koli's band of misfits. I will avoid too many spoilers and just say that the title certainly hints at this being the final book in the series and it does not disappoint. It wraps up the story nicely, especially for Koli's character, and the various PoVs all weigh in at the end so you get to experience the conclusion from all angles. This turned out to be an engaging post-apocalyptic series that manages to tell a unique tale and it is definitely worth reading. Note that if you are turned off by modern day topics like gender identity and gender affirming care being in your sci-fi stories, then you'll probably have issues with this one. 

I really enjoyed the linguistic decay that is ever present in the way the characters speak, and I feel it really enhanced the audiobook version. The narrators all did a good job giving this world and the characters a unique tone of voice, one that I haven't really experienced since Firefly. Definitely worth a listen.
