A time-bending love story between a prickly young woman and a carefree stranger, who are tasked with saving the universe—after accidentally destroying it in the first place.

Genevieve Newhouse and Ash Hargreaves weren’t supposed to meet like this. Unless it was always meant to be . . . 

Gen is a fastidious science prodigy with a chip on her shoulder, and she can turn herself invisible. 

Happy-go-lucky Ash has just escaped a sheltered (read: cultish) childhood, and he can manipulate time. 

The gifted eighteen-year-olds cross paths at the 1934 Chicago World’s Fair, where Genevieve’s experimental physics project causes an apocalyptic explosion. Ash tries to avert catastrophe by gallantly rewinding time a few minutes, but instead, he transports them back to 1893. The duo finds themselves trapped in an unfamiliar, unwelcoming era, with no idea how to return to their own time—or if their own time even exists. Their cataclysmic leap across decades might have destroyed the world as they know it . . . 

Fate and free will intertwine in this page turning historical romance that sets two irresistible strangers down a chaotic, potentially apocalyptic path. “Will they or won’t they” takes on a whole new meaning as Gen and Ash fight for survival while falling in love.
