An immortal, doomed to die. A time traveler, desperate to save her.When Zera travels back in time to 2040, she aims to investigate the geomagnetic storm that scorched the earth. Instead, she finds the beautiful Katherine, who speaks of past storms and asks with her dying breath, "Is this the first time we meet?"From WWII-era New York to early 2000s New Orleans and everywhere in between, Zera chases both storms and Katherine, thinking her immortality is the key to fixing the future. But as the immortal goes from a reluctant ally with a deadly hunter to a romantic complication, Zera wonders if the past is really set in stone, or if she can still save the world-and Katherine.
