A Time Traveler’s History of Tomorrow

Eighteen-year-old physicist Genevieve is thrilled to present her innovation on a particle accelerator called a cyclotron onstage at the 1934 Chicago World’s Fair. But when her device malfunctions mid-presentation, she’s saved from the fallout by time traveler Ash, who transports them both to 1893 Chicago. Soon Ash reveals himself to have been tasked with saving the world from purported annihilation brought about by the cyclotron. Having exhausted his powers, Ash is unable to return Genevieve to her timeline, prompting the teens to explore the past and encounter new friends, including Black academic secretary and mathematician Matilda. With help from Matilda, Genevieve discovers a way to get back home without relying on Ash’s abilities, but Ash’s commitment to his world-saving mission complicates matters. Via the white-cued protagonist’s cutting alternating POVs and the duo’s layered relationship with Matilda, Kulper (A Starlet’s Secret to a Sensational Afterlife) illustrates how race and gender inequality barred women and BIPOC individuals from scientific acclaim. Snappy dialogue, dynamic supporting characters, and robust worldbuilding further serve to deliver a satisfying combination of sparkling romance and whirlwind adventure. Ages 14–up.
