She couldn't be more ready.But the object changes trajectory. What was one object becomes three, seven, nineteen. Nineteen different modules land across the planet.When the nearest module creates a dome and leaves Aeris stranded within its confines, she's left to wander in search of safety. But things are stranger than she could have guessed, and she soon discovers she's not the only one wandering the alien landscapes under the domes.Alongside her 106-year-old grandmother, a displaced imam, the President of the United States and her bodyguard, Aeris must find a way home before they run out of water, food and ideas.The question is: when every direction reveals new and strange geographies, which way is the right way to go?
