First off, this is the third book in the Inheritance Trilogy. Not the second. I mistakenly thought this was the second one, but as all three books are standalone, it doesn't matter for the plot.
The Kingdoms of the Gods begins a little over a hundred years after The Hundred Thousand Kingdoms and follows the godling Sieh as a first person view.
There isn't really much I can say about this book I haven't said in my review of the first book in this series. We get some more insights in the minds of godlings, but that turns out to be quite mundane. They're just like humans, only with more power. The plot is once again a mystery type and solid enough to carry to the end.
If you enjoyed the first book, you can't go wrong with this one. The second book is likely fine as well as the story quality is consistent.
