I'm not sure why I really like this book. It's not super courageous, nor inventive -- it even leans a bit on existing fantasy tropes, but I love the way magic works in this world, and I also found the narrative situation engaging and mysterious. The idea of a series of books centered around an observer narrative that travels between worlds is marvelous for "plain fun" and sometimes when you read a book, you do it purely for entertainment. Lance Conrad succeeds here for me, and probably would for you too if you enjoy the genre.
Spoiler:
Overturning the tropes of a big final battle, the epic culmination of a group that travels spreading happiness and repair instead of conquest and destruction was something to revel in as a reader. When I hit that particular moment, I was boarding a bus, and I couldn't help but grin even though I had to set the book (kindle) down for a few moments to get seated. There's something purely euphoric and rightly human about this sort of ending, and it is the farthest thing from expectation in what I would generally think of as a fairly generic plot, with a chosen one, beautiful healing woman, a wise sage, a blacksmith father, exile, etc.
All in all, I really liked it, give it a read if you want a good time.
