This is our last review of a Cradle book, at least for awhile, since there aren't any more currently written. However, this is by no means the last book in the series, so I sincerely hope that Will Wight will be returning to finish the series soon. As amusing as it would be to be able to say that I read this book both first and last in the series, that mild amusement would not come close to balancing out the disappointment of not being able to find out how the series ultimately ends.
I came off of reading Ghostwater especially eager for this sequel, Underlord. Ghostwater provided a substantial amount of imaginative information about the deeper intricacies of the magic system, and I was hopeful that Underlord would give us the chance to see that new knowledge applied. Instead, Underlord gave us insight in an entirely different direction, involving the characters (and by extension us) in the fringes of world-wide political intrigue.
Of all seven Cradle books that have been released so far, Ghostwater was my favorite. This novel delivered on all of the promise that I perceived when I read the first book. It has the most robust character development of the series so far, digs into the technical details of the magic system, instead of just building out to the next level, and it gives insight into some fascinating aspects of the world and the story that have only been alluded to before. Perhaps most strikingly, it is drastically more imaginative than other books in the series, which is a testament more to the level of imagination involved here, than it is an insult to the imaginative level of the other books.
