I'm really glad that I suggested to the Ottawa Public Library that they buy this because it lived up to the promise of the first three novels in the series.

Without giving spoilers, it's fair to say that we learn more about what the Asiig are up to with Fergus.

The description for this book and Suzanne Palmer's own words say this is the final book in the series, but I hope she changes her mind. I understand nobody is going to publish a book where Fergus just goes about a quiet life having whiskies with his cousin, bantering with his sister and tending his cat, but it would still be nice to know what happens with the artificial intelligence things and to spend some more time with the weird aliens and semi-sentient space ships.
