Okay.. This one may have taken a minute for me to get into. It didn't start to really interest me until about the 30-40% mark. From there on it was a pretty awesome read. Although it has a simpleton, light quality to it, it was great watching how things unfold here. I loved the ending as well.
I may just have to tackle the other reads in the series. This is the 1st book I've read in this series. I was not lost or confused about previous characters and plots that are present here. Everything flowed really well without being overwhelming in the reveals.
I would say based on book 3, you don't need to read these in order, to enjoy the story.
