Persephone Effect is an absolutely incredible sequel  with a huge and all around amazing cast of characters which I feel deeply in love with. I cannot recommend not only PE but all of Gunmetal Olympus.

The lore it adds, the questions it answers and in turn raises, the despair and catharsis it elicits, the insane moments. It was a wild ride and I loved every second of it and I cannot wait to see what's next in GO!
