Abysm (Aurora Renegades Book Three). Amaranthe, #6

In the quest to be the masters of their own fate, will humanity rise to become liberators or follow the path of their ancestors into darkness?Alex Solovy and Caleb Marano risked everything to learn the hidden purpose behind the Metigen's multiverse portal network, but nothing could have prepared them for the answer.  Humans are a genetic recreation of the Anaden, the dictators and overlords of the master universe.
Aurora is a recreation of their origins, created by the Metigens in a desperate gambit to understand the nature of their enemy, and so find a way to defeat them. Instead it may turn out that history always repeats itself.. Aurora's future hangs in the balance as the Earth Alliance goes to war with itself over the right of synthetics and Prevos-human/AI hybrids-to exist. Terrorists sow chaos in a wave of bombings and assassinations targeted at any and all who shelter Prevos.
The next evolution of the human species will not be so easily defeated, however. Prevos, their friends and lovers, and all those who believe freedom is the better path forward meet malevolence with ingenuity, despair with hope, violence with fortitude.  But they must move quickly to win the day, because the true enemy is closing in faster than anyone realizes, and they-humanity, the Metigens and the trillions the Anadens enslave-are all running out of time.*It is a time of accelerating technological change and shifting allegiances as the old rules fall away and the old balance of power is upended.
A new world rises-one of unshackled AIs, indestructible starships, ethereal quantum spaces and potent new weapons-and the race is on to determine who will control its future.
