A Time Traveler's History of Tomorrow

by Kendall Kulper

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.

Modern-thinking woman collides with care-free time traveler. Both have to learn to live with consequences to their actions. I've never seen so much youngest child energy in one book and personally (though I'm an eldest child) I am here for it, it was so darn entertaining.

I think the first book in this series remains my favorite but this one was so much fun! Time travel can be a tangle-y, sticky thing, but Kulper navigated it with admirable poise. The science angle was interesting (though, if I'm honest, I didn't understand half of what Genny was talking about but. that's on me, that's not on the book LOL). Ash is an absolute cutie patootie, and I adored the partnership and eventual love that blooms between the pair.

I'm so glad we've seen the stories of all three Newhouse sisters, and I can't wait to see what Kulper does next! 4.5 stars from me!

A Time Traveler’s History of Tomorrow by Kendall Kulper is a run-of-the-mill young adult historical fantasy.

Although apparently part of a series (each book follows a different Newhouse sister), this book can be read as a standalone. It follows two young characters from 1934 Chicago: Genevieve, an ambitious scientific genius desperate for the patriarchal scientific world to recognize her discoveries, and Ash, a young man who recently escaped from a fundamentalist doomsday cult. They both have special powers—Genevieve can turn invisible and Ash can turn back time in small increments. Ash visits the 1934 Chicago World’s Fair because the cult leader told him the world would end at the Hall of Science on July 15, 1934. That same day, Genevieve heads to the Hall of Science to demonstrate her cyclotron to an elite scientific audience after winning a prestigious fellowship. When Genevieve’s demonstration goes wrong, she and Ash end up time traveling back to the 1893 Columbian Exposition.

A Time Traveler’s History of Tomorrow is one of the okayest books I’ve read in a while. I picked it up because I have a longstanding love for the Columbian Exposition and time travel stories, but my expectations were not terribly high. I appreciate some of its character moments and its feminist, anti-bigotry perspective, but it often feels dull and hamfisted in the way that many young adult books do. Every time I found myself impressed or enjoying myself, I was quickly brought down by something trite or cringeworthy. As a result, I spent the entire book feeling totally lukewarm about the experience.

I would recommend this book to younger teenagers interested in science and history, but older readers can find more entertaining and complex stories elsewhere.

I, too, would like a coat with pockets large enough to hold several hefty books.

This time-traveling romp is an ode to science girls, the brilliant minds held back by prejudice, and the small pebbles that start avalanches. It’s 1934. Genevieve is bursting to share her latest scientific discoveries (never mind that the foundation thinks she’s a boy - they won’t have time to change their mind on the spot); Ash is headed for the same event, not sure what he’s looking for other than that something in the World Fair is going to bring the end of the world. When things go wrong and Ash’s time travel ability takes them to the year 1893, it’s up the disgruntled duo to return to the future and prevent the apocalypse which they may have unintentionally wrought.

Genevieve and Ash jump off the page, and while their mystical abilities aren’t fully explained, they clearly stem from key moments in their lives and continue to shape and be shaped by their identities. These connections are slowly revealed as the two get to know each other, and confront truths about themselves, and the underlying emotion is deeply relatable (the fear of being seen, for example, or not being seen by those one loves). There’s also a cultish commune, dire predictions, and skulking in labs and libraries. Genevieve is a budding physicist, so there’s a fair amount of science babble that may or may not be as far-fetched as her invisibility power, but as a non-physicist myself, I’m happy to accept it for the story. Is it actually feasible to build a cyclotron in the backyard greenhouse and discover a new element? Debatable, but if anyone can, it’s Genevieve.

Apart from the jump back to 1893, the time travel is largely limited to minute/hour changes. Rewinding a conversation, etc. So while there is an inevitable discussion of time loops and paradox, it’s not a narrative focus, and I slide it into the same category as the science babble - might trip up hardcore sci-fi fans or PhDs, but it works for me.

I read this as a standalone, but apparently it's the latest in a set of companion novels that feature Genevieve’s sisters. I'm excited to pick those up.

3.5 rounded to 4 stars.

Ash can travel back in time. Genevieve can turn invisible. When they get together, the world ends. Luckily the same event pushes them back forty years so they have a chance to save it. I really like the characters of Ash and Genevieve. Their backgrounds really drove home the setting of 1934 (and then 1893).

The biggest issue that hurt my enjoyment was their lack of chemistry. I think it would have been a more powerful story if the two mains were just friends. We don't see that enough with two heterosexual characters of separate genders. I don't understand why not. It would have worked so much better considering how they interacted. No banter, no flirting, no connection except being trapped together, then bam, they're kissing. I didn't find their attraction believable.

The second problem that kept throwing me out of the story were their powers. The book talks all about scientific discovery and scientific method and searching for the truth. Yet, they have these weird powers that no one else has. When their allies discover their abilities, they're like "checks out." No fight, no disbelief, no oh yeah bob used to bend spoons with his mind so I could see this happening. Nothing.

The coolest part was the story and how it unfolded and the struggles they overcame to be successful, even if that definition had to change as they progressed. For that I'd probably read more by this author. Though I'm truly confused by the author acknowledgments, where she mentions this being the end of the series. I can't find that this is a series anywhere and it certainly didn't feel like one either.

Rating: 4.5 stars

I really enjoyed this Young Adult time travel book! I loved how it was set in 1934 with the end of the world and then the characters were pulled back into time to 1893. This book was set in Chicago and I loved the uniqueness of the story. I loved how both of the characters grew, how they learned to let others in and trust people, and how maybe you can't always take back what you say, even if you really wanted to. Both characters had their own unique abilities and I enjoyed that about them. This story was very well written and I honestly didn't want to put it down, especially towards the last half of the book. If you enjoy a good time travel YA historical fiction, then I definitely recommend this one!

I received a complimentary copy of this book, which does not impact my review.

[Abigail Evans · Rating 5 out of 5]

this was such a good book! it was so cute and fun and I enjoyed almost every bit of it! there were a few things that I didn't like about it. one being just a quick mention that Ash had a brother who was actually a girl😬 and the other being that Ash and Genevieve had dated for FOUR YEARS and weren't married by the end(come on yall). I also was a little irritated by Genevieves feminist agenda but it wasn't as bad as it could've been. overall 10/10, I'd definitely recommend. 😁

A Time Traveler's History of Tomorrow is a historical sci-fi following a girl who can turn invisible and a boy who can slide through time. They get sent from the 1930s to the 1890s, and must find a way to get home.
The atmosphere of the story was done well. The setting of the Chicago World’s Fair in both the 1930s and 1890s was described really well, and it felt historically grounded.
I’m not sure what part of this book didn’t click, but I wasn’t super impressed. Despite the plot twists, this book reads like a fairly standard time-travel story. The second half was much better than the first, but the final ending didn’t feel properly resolved and left me disappointed.
The majority of the characters lacked true depth, despite having really interesting backstories. Even Matilda, my favorite of the characters, only discussed being a Black, female scientist with surface-level monologuing. The romance between Ash and Genevieve wasn’t interesting to me, and Ash deserved way better than her.
There were some interesting elements to this story, but ultimately it was just alright. There were parts I enjoyed, but I don’t think this book will linger in my memory.

CW: sexism/misogyny; racism; classism; cult & harmful religion; death & grief (sibling)

What a fun story! I haven’t read Kulper’s other novels that feature Genevieve’s two older sisters, but I love how the author weaves in commentary on the silencing of women and people of color in the scientific world. And the time travel elements between the two World’s Fairs— the 1893 Columbian Exposition and the 1934 Century of Progress— were so well done.

In 1934, Genevieve Newhouse is a bright and brilliant upcoming physics prodigy that feels invisible to her male colleagues and to her family. Ashley (“Ash”) Hargreaves is a young man who has grown up in a sheltered community run by a religious zealot. Both worlds collide at the Chicago World’s Fair where Genevieve (using an assumed male name) is set to give a presentation on an experimental project. Ash is there under the impression that the world is going to end and he believes he has the power to stop it. When the two events align, Ash and Genevieve are sent time traveling into the past where they are desperate to change the future for both their sakes. A Time Traveler’s History of Tomorrow is a fascinating sci-fi tale mixed with a hint of romance that may, in the end, be a bit lackluster, but will have you turning page after to page to see what the future holds.




It is the year 1934 and Genevieve Newhouse is a young woman who possesses the brains to change the face of the physics community with her invention of the "cyclotron." However, her intelligence is often overlooked due to the gender bias and misogyny of her time. Under a gender neutral name, she submitted herself for a research fellowship and won. Genevieve hopes that by surprising her peers and presenting her device at the fellowship award’s ceremony at the Chicago World’s Fair she will get a real shot at becoming a world renowned physicist. While often ignored by others in her career field, Genevieve also feels overshadowed by her better looking and more amiable sisters - so much so that she feels invisible to the world. In fact, that invisibility has manifested into Genevieve actually being able to make herself invisible. 




Ash Hargreaves has grown up in the secluded town of Harmony run by a man known as Father Daily who seemingly has a knack for predicting catastrophic events. Father Daily has determined the world is set to end on June 15, 1934 at the Chicago World’s Fair. Ash firmly disbelieves Father Daily’s visions, much like his brother Archie had before him. Archie went on to leave Harmony and lost his life along the way. Still, Ash doesn’t agree with Father Daily and is determined to keep the world from ending. He heads to the Chicago World’s Fair Hall of Science to see what he can do in order to prevent the event - hoping to use his hidden talent to turn back time to keep this catastrophe from taking place. 




The two worlds collide when someone who doesn’t know what they’re doing attempts to use Genevieve’s cyclotron - causing an explosion that Ash tries to take back with the help of his time traveling capabilities. Unfortunately, this perfect storm sends the two back in time to 1893 where they must find a way to change the future while also returning to their proper place in time. A Time Traveler’s History of Tomorrow follows the adventures of this likable duo as they attempt to blend in with the time period, along the way finding an ally that will help them figure out a way to get back to 1934 and save themselves and the world.




Author Kendall Kulper offers Back to the Future time travel elements mixed with "The Umbrella Academy" abilities and apocalyptic vibes with a romantic twist, which causes Genevieve and Ash's time together to unite them in more than one way. Neither of the two have ever felt truly seen and heard, which has them sweetly finding common ground and racing hearts while simultaneously working to assist in saving the world. Be warned, there is a major twist that readers won't see coming and might make the trajectory towards the finale feel a bit muddled. Regardless, the chaos, the abilities the characters possess, the path towards self-confidence and potentially apocalyptic events are what keep readers invested. 




A Time Traveler's History of Tomorrow places two strangers down a "will they or won't they" trajectory in more ways than one and that's what makes the book worthy exploration. Where science meets sci-fi, readers will find themselves intrigued and hoping there is a world beyond the 1934 Chicago World's Fair.

Thank you NetGalley and Holiday House for the ARC in exchange for an honest review!

“A Time Traveler’s History of Tomorrow” by Kendall Kulper is a smart, energetic YA time-travel adventure that combines historical fiction, science fantasy, and romance into a story about consequence, courage, and learning to be seen. Set primarily in 1934 Chicago, the story follows two very different teenagers whose collision across time may determine the fate of the world.

Genevieve Newhouse is a fiercely intelligent, modern-thinking young woman desperate to share her scientific discoveries in a world determined to dismiss her because of her gender. Ash Hargreaves, on the other hand, is a carefree, charming time traveler who knows only that something at the Chicago World’s Fair is going to trigger the apocalypse. When events spiral out of control, Ash’s time-jumping ability sends the pair hurtling back to 1893, forcing them into an uneasy partnership to repair the timeline and possibly undo a catastrophe they themselves may have caused.

The dynamic between Genevieve and Ash is one of the story’s greatest strengths. Gen’s meticulous, no-nonsense approach to science contrasts beautifully with Ash’s impulsive, emotionally driven nature. Their banter is lively, their conflicts feel earned, and the slow evolution of their partnership into something deeper is both tender and satisfying. While Genevieve can come across as harsh at times, her guarded personality is clearly shaped by a lifetime of being underestimated, and the novel thoughtfully ties her invisibility powers to those emotional scars. Ash, meanwhile, is endlessly endearing; his character has humor and heart, which helps balance the story’s heavier themes.

Kulper handles time travel with admirable confidence. Though the book includes discussions of paradoxes, cause and effect, and apocalyptic stakes, it never becomes bogged down in technicalities. Much of the time manipulation focuses on small rewinds like conversations undone and moments reconsidered, which keeps the story grounded and character-focused. The science elements did feel a bit dense at times with some info-dumping, but they do serve the story well, especially in highlighting Genevieve’s brilliance and determination.

The historical settings are richly rendered, from the bustle of the 1934 World’s Fair to the earlier Chicago of 1893. Cultish communes, secret labs, libraries, and dire predictions add layers of intrigue, while the plot steadily builds toward a twist that feels both surprising and perfectly earned. Though the pacing occasionally slows, the emotional payoffs and bursts of action more than compensate, especially in the latter half of the book.

Overall, “A Time Traveler’s History of Tomorrow” is a story about responsibility. How even small choices can ripple outward and about learning to trust others when the world has taught you not to. It’s a celebration of brilliant girls in science, imperfect heroes, and the messy, beautiful ways people change one another.

This was a very rare misfire from Kendall Kulper, whose books are usually fantastic (including the other two in this series).

I will presume the best of intentions in the writing of this book – timey-wimey romance, celebrating women in science, and so forth. Unfortunately, none of those good ideas landed in the execution.

This series of books have all addressed the systemic injustice of past eras, but in this one, it’s with a decidedly 2020s bent. The characters are all chirping about intersectionality, “what about women AND people of color AND so on.” They also seem to treat everyone who isn’t getting with the ahead-of-their-time program as a mustache-twirling villain hell-bent on intentionally doing evil… which really seems to run contrary to the messages that the inequality is systemic, rather than the work of a few bad apples.

That overly simplistic portrayal is a flaw that pervades the text. After a twist that was genuinely brilliant, which I didn’t see coming, the book never quite commits to the idea that zealotry can bury even the most wholesome of intentions. I thought Ellery becoming Father Daily was so clever, and was setting up a really compelling “What if a good guy today is tomorrow’s supervillain?” ethical dilemma. But nope… it turns out that, after four decades building a cult, all Father Daily needed was to hear that a few people in the crowd were unhappy with his message. That never occurred to him before? The shock of his acclaim being not wholly universal gave him a heart attack or something and made him disappear for good? God, we should be so lucky with our cult leaders… has anyone tried telling Trump that a few people don’t like him?

While I concede that time travel is very difficult to pull off without opening up gaping plot holes… it’s very sloppy in this book. I kept being pulled out of the story by the lack of logic. Why does Genny forget everything at first but Ash doesn’t? Why does the “time tunnel” take them back to a different time than they left? And, for heaven’s sake… if they’re so damn worried about forgetting things, why not write something down, given that they can take things with them when time traveling? It seemed like the rules of time travel were whatever propelled the story, and that’s about it.

I’ll give this book credit for Ash being a fun character, charismatic and easy to root for. Gen is much harder to like, given her whole thing is feelings of inadequacy while also being convinced she’s brilliant, two aspects that are hard to reconcile. Their romance is… fine, I guess; both of them and the book seem far more concerned with Ellery/Matilda/time travel than with each other.

I’m bummed this book didn’t work for me. Luckily, all three books in this series are totally standalone, so I can still enjoy the other two books and never concern myself with Genevieve again.

[Steff Fox · Rating 4 out of 5]

A Time Traveler's History of Tomorrow was honestly such a fascinating read. I'll admit that there were definitely some slow moments where I got a little bored, but the moments of action truly do make up for all of that. And that plot twist? My goodness, I really should have seen it coming and I think I was a little off my game while reading this book. For me, it's not the predictability or unpredictability of a twist that makes it good but rather how well it fits into the story, and boy let me tell you this one fits so well.

Of all the characters, I admittedly loved Ash the most. Both his experiences and choices throughout the novel were deeply engaging and some of the biggest strengths of the whole book. I do feel a little bad for admitting that Genevieve wasn't my favorite, largely because the reasons behind her personality are fully understandable and I do deeply appreciate what she represents for women. She was definitely a little harsh and forceful, a direct result of the world she grew up in and their abject dismissal of women for simply being women. I also really appreciated how this all played an integral role in the understanding of her powers.

In that regard, I will say that the time travel and how it affects the plot is truly the shining star of this novel. The characters are pretty good, but I don't think I'd say they were phenomenal, which is why some of the book ended up feeling rather slow for me. I did love Matilda, though, and her inclusion in the novel was certainly a high point as well. Outside of that, I think the main reason why I rated this book as highly as I did was very much just the plot. I just really appreciated the aspects related to time travel.

I received a copy of this book from NetGalley in exchange for an honest review.

[Michael Doane · Rating 5 out of 5]

A Time Traveler’s History of Tomorrow is a clever, emotionally grounded time travel romance that balances high concept science fiction with the tender awkwardness of first love. Kendall Kulper brings a playful intelligence to the genre, weaving fate, free will, and historical spectacle into a story that feels both expansive and deeply personal.

Genevieve Newhouse and Ash Hargreaves make a compelling, opposites attract pairing. Gen’s tightly wound brilliance shaped by ambition, insecurity, and a need for control contrasts beautifully with Ash’s openhearted curiosity and hard won optimism. Their powers mirror their inner lives: invisibility and time manipulation become metaphors for being unseen, out of sync, and desperately trying to fix what’s already broken.

The novel’s historical settings, from the 1934 Chicago World’s Fair to the 1893 Columbian Exposition, are richly imagined and thematically resonant. Kulper uses these eras not as mere backdrops but as pressure chambers, forcing the characters to confront questions of progress, belonging, and responsibility. The result is a story that understands time travel not as escapism, but as consequence.

At its heart, this is a book about choosing connection in the face of uncertainty. The “will they or won’t they” tension is sharpened by genuine stakes: the possibility that love itself might alter or erase the future. Kulper’s prose remains accessible and brisk while allowing emotional moments room to breathe, making the novel especially appealing to readers who crave romance with substance.

A Time Traveler’s History of Tomorrow is a smart, heartfelt addition to YA speculative fiction one that reminds us that saving the universe often begins with learning how to trust another person.

Do you know how hard it is to find a good sci-fi book WITH romance?!!! this book was such a find and it was worth the 324+ pages. I loved Genevieve and her struggle with metaphorically (and literally) feeling invisible like same twin I understand you 😔✊ I wished her relationship with her siblings was show a little more (especially with henny) but besides that i enjoyed reading this book so much, i loved the romance with Ash and Gen and LOVED the representation of the struggles to be a female genius back when that wasn't acceptable (women in male-dominated fields.) Reading how people from 1934 and 1893 viewed women made me a little more grateful to be born in the current day and proud of how far we've come as a society even though bias towards women in science and sports fields is still an issue. Overall this was an amazing read and i am so happy i managed to find this gem of a book 💖✨

This was pretty fun and so much different from A Starlet's Guide to a Sensational Afterlife! I like how all three books are centered around the different sisters and have very different stories. Even though I've only read the book about Henrietta and this book, I still enjoyed both stories nonetheless.
I also enjoyed reading about Ash and Genevieve's dynamics. It's refreshing to have a male lead who is carefree and of average intellect like the average person haha. He is a good balance to Genevieve's personality, where she is super smart, but sometimes she cares too much.
I think the epilogue was also pretty well done, with the author explaining about how Ash and Genevieve went about their lives afterwards, along with the impending events.

I hope the author continues to write more books in the future as I truly enjoy her writing style.

A Time Traveler’s History of Tomorrow is an ambitious and imaginative romp through time, brimming with clever twists and romantic tension. The premise, two gifted teens accidentally unraveling reality and falling in love while trying to fix it, is undeniably fun, and the historical settings are vividly rendered. However, the story sometimes gets tangled in its own complexity, with uneven pacing and character development that doesn’t always match the high-concept stakes. Genevieve and Ash’s chemistry shines in moments, but their emotional arc can feel rushed amid the time loops and paradoxes. Still, it’s a creative and entertaining read that will appeal to fans of quirky, science-tinged romantasy, even if it doesn’t quite live up to its cosmic potential.

This was phenomenal! I can't understand why the overall rating is so low. I love a smart, science minded historical fiction YA heroine (Genevieve). The male protagonist Ash compliments her personality perfectly. These characters felt so real to me.

The twist!! Ash's new friend being someone haunting from his past. I was absolutely shocked and didn't see it coming at all.

I adored that this was a self discovery journey for both protagonists. The story was engaging and exciting. I loved it!! I'm satisfied by the ending but I want to read more about them.

Always appreciated YA historical fiction that doesn't focus on WWII because there's not a lot of it. That made this feel fresh in a way.
