I'll be generous and round up 3 1/2 stars to 4, because I do love these characters and the world and, overall, the return to the topics and storytelling of the first.
So yes, I really liked it, but I also had some nitpicking problems with pacing and descriptions. There were several passages in the beginning that felt like she was explaining the novel to new readers a bit clumsily, but then other passages that clearly relied on the reader having read the previous novels, so I wasn't sure what the point of the first parts were.
Anyway, if you've made it this far in the series, and especially if you preferred books 1-3 to 4+5, then I heartily recommend this one. What it does well--character, plot, world-building and intrigue, more than makes up for the nitpicky shortcoming.
