When luminous beings descend from the sky, humanity calls them angels-but these aren't the winged messengers of scripture. They're energy-based life forms offering impossible gifts: instant teleportation, miraculous healing, and technology beyond human comprehension. All they ask in return is partnership by bonding with individuals of their choice.For John Higgins, a veteran haunted by tragedy, his angel Hoopie brings unexpected peace from years of PTSD. For his wife Grace, a Philadelphia news anchor, her companion Whisper offers enhanced perception that revolutionizes her reporting. But as humanity embraces these otherworldly allies, building homes that think, growing crops in minutes, and traveling between planets in seconds, a darker truth emerges. The angels are refugees, they're fleeing across the cosmos from an ancient foe. And they've just led that enemy straight to Earth. When billions of demons-parasitic entities that consume consciousness itself-descend upon our world, humanity faces extinction. The only hope lies in merging human and angel species into something unprecedented, something powerful enough to fight back. But becoming humanity's salvation may mean ceasing to be human at all. As society divides between those who embrace transformation and those who violently resist it, John and Grace find themselves at the center of mankind's evolution-and its greatest battle for survival. A thrilling first contact saga that asks: When salvation requires surrendering everything that makes us human, is the price of survival too high? Or is it exactly the leap forward our species needs?
