Olivia Nikitas, a hardened journalist whose niche is war zones, continues to be reporting from the front lines of the civil war in Aleppo, Syria. When Brian, an aid-worker she reluctantly fell deeply in love with, dies while pursuing her into risk, she’d perform anything to bring him back. Within a makeshift loss of life chamber beneath an ancient, sacred site, a unusual technology is exposed to Olivia: the power to remake the near future by changing days gone by. Following her heart and not her head, Olivia brings Brian back again, accidentally shifting the world towards the brink of nuclear and biological disaster. Now she must stay measures ahead of the guardians of this technology, who will destroy her to reclaim it, to conserve not just herself and her like, but the entire world.
