I liked these stories far more than the main series. The gods are actually recognizable, acting like their mythological counterparts. I particularly appreciate the fact that most problems are caused by Zeus in some way or another. I liked the stories of Hera, Aphrodite, Persephone, and Hermes, but was not a big fan of Hades' story. I could empathize with Hera, Aphrodite, Persephone, and Hermes in their situations, but grew frustrated with Hades who would not even attempt to move on with his life until Demeter basically forced him to try. And the beginning signs of instant love at the end of his story did nothing to improve my feelings toward his story.
With the exception of the last story, I was pleasantly surprised with this book. These were the depictions of the Greek gods that I expected from the main series, but failed to find.
