Months after the battle that almost destroyed everything Steve and his friends worked for, the world seems calm. The little town on the ocean has become an island called Bastion, with its powerful beacon drawing wary travelers to safety.

Steve knows he should be thankful, but he can’t get over everything that has led up to this point. With the evil defeated and his powers now only a distant memory, Steve feels lost; unsure about his purpose in this strange, changing world.

What Steve doesn’t know is that the world is about to open once again. As Alex begins to act differently and warns of impending destruction, Steve finds himself in a city larger than he ever thought possible.

Friends and enemies both new and old emerge from the shadows, and Steve finds himself enthralled in a mysterious mission: to break into a luxury party at a museum and find the key to stopping a war between two cities.
