I absolutely loved this book. There's a lot to talk about, but it's hard to do so without spoilers. It's an unconventional narrative, with multiple POVs that seem very disparate, each with completely different types of worldbuilding and styles. Initially, this made it a bit harder to get into the book, especially because of how bonkers the worldbuilding is, but as I started to realize the way all the threads were being woven, I really appreciated how audacious it was. Pieces start clicking into place throughout, and maybe a few people would get annoyed at how it's all framed, but the puzzlebox structure was perfect for me. In fact, this book utilizes a narrative mechanic that I've always felt would have been fascinating to do in a book but had yet to ever see even really attempted. At times, you even have chapters where an in-world historian/scholar will try to analyze the events retroactively because so much of this book is piecing together the history of what has happened and how it influences what is happening and the characters' decisions. It leads to some unique character work as well. A sci-fi post-apocalyptic fantasy. It's about a dying world where light is disappearing and true dark encompasses everything. A world where a sleeping giant is imprisoned beneath the ground. Where people from a different (our) world can enter and be essentially gods. A world filled with machines, a group of wizards that disappeared, and an eclectic group of movers and shakers trying to make plots within plots within plots. And at the heart of everything, a bunch of lost children who all received a dream, a dream of trees, and grew up wanting to save the dying world. Highly recommend, 5/5 (edited)
