I was lucky enough to beta read for this book. It's a fantastic addition to the Cradle series.
Stylistically, I feel like it's closest to the very first book, with Lindon spending a considerable amount of time exploring and learning about a part of the world virtually on his own. This style has advantages and disadvantages, but most importantly it means that he doesn't have the benefit of powerful allies that can intervene and save him at any moment. This lends a real element of risk and tension to the book, and that helps to allow Lindon to grow.
We also get some great moments with other characters, including some much needed development for Mercy and my personal favorite Cradle character, Yerin.
All in all, it's a great book and I strongly recommend it.
