Dominion. Children of Aurora, #2

Humanity escaped Earth to build a free world. Now Earth has found them. The people of Aurora have endured war, alien predators, and the dangers of an unexplored planet to create a civilization founded on freedom. Across the Star Portal, the Covenant has rebuilt humanity through order, obedience, and conquest. Now the two worlds are on a collision course. President Tina Hammer and Ramon Solis are trapped inside the Solar system, where they uncover preparations for an invasion of Aurora.
Every attempt to sabotage the Covenant's plans brings them closer to discovery, while an imprisoned Susan Atlas struggles to convince its ruler that war could destroy both civilizations. On Aurora, ancient systems are awakening beneath the planet's surface. The Star Portal is changing, hidden connections are emerging, and the mysterious Thomas Dunn may hold the key to secrets that have remained buried for thousands of years.
As soldiers gather and old loyalties are tested, Aurora must prepare to defend everything its people have built. The Covenant, on the other hand, believes humanity can survive only under a single authority. Aurora will never surrender its freedom. Dominion is the second book in the Children of Aurora series, an epic science-fiction adventure filled with military action, political intrigue, alien mysteries, interstellar exploration, and the gathering storm of war between worlds.
