I enjoyed this book and it is very similar to Cradle/Unsouled in its tone/writing.
Suitable for teenagers.
If you enjoyed Cradle/Unsouled then you will most likely enjoy this and hey Free is Free!
First book ended pretty well in my opinion there is 3 other books as well.
I gave this book a 4/5 which I consider recommended read. Again if you enjoyed Cradle/Progressive fantasy you will like this.
