Alien Visitors. A Global War. An Unavoidable Extinction Event.
A 2018 Breakthrough Fiction Award Winner in Science Fiction.
When Earth's ecosystems begin to fail, an ancient race of galaxy stewards intervenes and attempts to save the dying planet.
It does not go well.
Powerful and corrupt corporate and governmental entities ignore the steward's warnings and incite regional wars --- igniting global conflict and accelerating the planet's death spiral.
Fearing extinction, many humans join with the stewards as they hastily assemble an exodus of children into deep space to ensure the survival of humankind.
Will they succeed in saving Earth and its progeny before it's too late?
