Horizons (The Last Dawn, #3)

Who is in control?
Michalla, A J, and Harlee arrive at the ARK—America’s last place of hope—and soon discover that the surviving leaders of the free world are running the show. When those leaders try and force the trio into a series of questionable experiments, they must choose to remain in relative comfort, or set out on their own again in search of a better world.
As the saga of the Dresdon family continues in The Last Dawn: Horizons, ordinary people must find extraordinary ways to survive. Society has collapsed from a devastating virus that has killed most of the humans who inhabited the planet.
Noah, Cori, and Dak, continue their search for Michalla as the few survivors of the apocalypse fight to stay alive. They must find her.
