I would agree with others this is just average, to a bit above average. I cannot go into much detail as to not spoil anything and some may consider this so just note I would give it a 6. If you read the maybe spoiler and are okay with it then I would give it at least a 7, as it did mix things up and I did not see certain things coming. I read a lot so most things I see coming as they were already done by someone else.

*Maybe considered spoiler* The ending is not closed right. In fact it is left open ended. This ruined it for me to end with the same problems the world started with. If there was nothing that could be done then it is fine but that is not true. At the end of the book series all the knowledge on how to stop their issues is acquired by our main hero, and within there abilities even if it was over time. Even though there will not be another book written this one was not closed out even with such a good available. I problem solve for a living so I ruin books like this for myself a lot but this one was super easy to see the solution to.

Which was sad because it did do a lot of things differently and mixed it up so much even sometimes I was ow man this is going weird places and I do not know if I like it but in the end it was different and I did enjoy the writing style
