Books in the Unnatural series

Throughout human history, supernatural beings have existed. Technically only mutant humans, they were once revered and considered god-like. But now, they have been renamed as Unnaturals, and are hunted by radical humans as prey for medical and military experimentation and advancement. Placed in Institutions all over the world, many never make it out alive. Having enough of the inhumanity and abuse, Rebels have created safe Sanctuaries for the Unnaturals, freeing them from cruel lives in Institutions and helping them carefully re-enter society filled with humans who fear and despise them. However, when one Rebel frees a unique breed of Unnatural that's rarely been seen in the past hundred years, they have no idea what they are getting themselves into...

As a child, Cinder was unknowingly chosen by Zachariah, an arrogant fallen God who was simply seeking a new plaything. Augustus, a charming yet mysterious Human follower of the Fallen God, was ordered to oversee her progress towards becoming a Fiend, otherwise known as a God's obedient servant. Crushed and heartbroken from her latest losses, Cinder realizes her entire existence has been laid out in front of her, and she's doomed to live as a slave under an unruly God's thumb. Having Cinder as his Fiend, Zachariah believes it will undoubtedly secure his place back on his besieged throne. While Unnaturals and Humans continue to tear each other apart, Augustus realizes that Cinder isn't who they thought she was. Born with terrible genetics and broken by traumatic memories, Cinder can only take so much before she shatters completely. Can she handle the cruelty of love and Gods? And will she ever be free again?
