While not normally a fan of same-universe stories that aren't about the main plot of a saga, say, with this book being a supplementary book to the The Expanse series, I have to say that Jim Butcher rather broke me of that dislike with the extra Harry Dresden books. When you enjoy a series a lot, you want whatever sized book and whatever plot line the author (or authors) want to write.
Such is the case with this book.
In this book, we have a glimpse into Bobbie's world after her ordeal, "treason," and homecoming from Abaddon's Gate. It's only a glimpse, as the story is actually about her nephew, but that's okay, because we learn more about the universe, more about the school systems, and more about Bobbie. All good things.
I enjoyed this book a bit, it being in the Expanse universe and all. If you're reading and enjoying the series, include this one in your reading.
Now, where's my rocketship?
