Tower Apocalypse 4

The walls are closing in.

The more Devin Cain learns about Gaea, the more dangerous it appears. After finding a hidden shard of the broken Demigod Parfanel, Devin has become more powerful than ever-but that same power has also drawn the ire of the Demigods and the System.

He's already united humanity and won the dwergar to his side, but even an alliance of thousands won't be enough. When Devin and his friends decide to risk it all and escape Gaea's death games, they'll find themselves in a struggle unlike any they've faced before.
