I’ve got to say at the top of my review, the most impressive thing about this book is the power scaling. It never gets out of control. It has been four books, and I feel like the characters still have room to grow. Not just power scaling. They also have room to grow in just about every conceivable way, and I look forward to the next book find out the rest of the story. The narration was top-notch and really puts you in the scene.
