A Game of Gods

Personally, I think this is the strongest book out of both sagas. Seeing how the Olympians and gods interact with and adapt to (or don't) the modern world has always been my favorite, and there's plenty of that in this.

When you tell the same story from a different point of view, it can be challenging. Hades and Persephone's story arcs are independent enough that there's plenty of space for this to feel fresh.

The action scenes were well done and dramatic.

This book includes chapters from multiple characters, and while I normally dislike changing that so late in a series, it felt natural and was necessary for this book to feel complete.

The only downside I can think of is that you get stuck with the same cliffhanger twice, but that's kind of part of the fun isn't it?
