I have made it a policy here on the site not to post reviews for books that I read in the past. That is, while there are many books that I read before starting this site and before starting weekly reviews on the site, I only intend to post reviews for those books if I actually sit down and re-read them. In some cases, like for books that are a part of ongoing series, that means that reviews for the older books will likely be posted eventually as I re-read to get caught up for a new release (like we did for the Stormlight Archive books). There are a lot of books that I would like to add to the review collection that I've already read, but with a reading list as long as mine is, it is increasingly challenging to justify spending too much of my time re-reading books.
Unsouled, and the Cradle series as a whole, is described as something called martial arts fantasy. The magic system has defined levels of skill, with each skill level gaining distinct abilities and possessing unique attributes. It's not a design that I generally prefer, but it worked well in Unsouled. Which matters, because Unsouled is not necessarily the kind of book that you read for the compelling characters or political drama. You read it for the vivid magical fights.
