Time travel in science fiction has always been a fascinating yet challenging concept, teasing stories with endless potential while bringing its own unique set of headaches. Taking a bold step into this tricky domain of complex timelines and tangled paradoxes, Philip Fracassi brings us The Third Rule of Time Travel, a novel where the weight of memory and grief takes center stage.

The novel follows scientist Dr. Beth Darlow, who along with her late husband Colson had been developing a machine that allows the transport of the human consciousness through time and space. However, this form of time travel has limits. First, you can only travel within your own lifetime, so forget about going back to the dinosaurs or witnessing the fall of Rome. Second, there is no reliable way to know when and where your consciousness will end up, only that it can travel for no more than ninety seconds. Third, over the course of these ninety seconds, no interaction is possible, only observation. Due to the restraints on this particular tech, these three rules are immutable, with many mechanisms put in place to ensure that sending an individual’s consciousness to the past should not alter the present.

In the aftermath of Colson’s death, Beth is left to raise their young daughter on her own. She throws herself into her work, using the time machine to gather more data. But as the pressure mounts, her trips into the past become increasingly dangerous, with the machine seemingly to force her to relive her most traumatic moments. For Beth, whose life has been marked by plenty of grief—including the tragic loss of her parents and older sister in a plane crash during a childhood vacation, and Colson’s fatal car accident on her last her birthday—these painful memories threaten to shatter her. Then, a disturbing anomaly arises in the form of a discrepancy discovered between reality and the failsafe method designed to monitor changes in the present timeline. As the line between what is real and what is not begins to blur, Beth must do everything she can to hold onto her loved ones and her legacy.

Fracassi’s storytelling in The Third Rule of Time Travel is a riveting mix of fast-paced action punctuated by poignant, emotional beats. Tragedy has followed Beth since she was a kid, and the novel kicks off with a harrowing opening sequence, putting us in her head as her consciousness is transported to the worst moment of her life, as a way to introduce its time traveling elements. From this point onwards, the plot maintains strong momentum, keeping the interest going by making the reader care about Beth’s personal and professional life. The cutting-edge descriptions of the story’s time traveling method alongside the top-secret nature of the character’s work made it easy to keep turning the pages.

When it comes to characterization, Beth Darlow is a layered and sympathetic protagonist whose strength lies in her determination to keep living despite the recent loss of her husband, juggling both the important roles of scientist and now single mom. At home, she struggles with the guilt of hiring a nanny and having less time to spend with her daughter, while at work she seems to be constantly fighting time and funding constraints placed upon her by the company’s higher ups. But while this is undeniably Beth’s story, I feel that some of the supporting characters—the best friend, the research partner, the hard-ass boss, etc.—could have been better fleshed out to give the novel’s premise a more convincing boost.

There are also moments where this book stumbles under the weight of too much exposition, though going back to the complexities of time travel, I suppose a certain amount of info-dumping is to be expected. Most of these sections were thankfully brief and didn’t affect the pacing too much, and to his credit, Fracassi managed to get a lot of detail and explanation across without making it boring. Ultimately, the unique “three strict rules” imposed upon the author’s version of time traveling resulted in a thought-provoking read, emphasizing the psychological impotence one must experience when reliving a terrible life event with no power to change its course. That said, as is often the case with time travel stories, I didn’t feel like it stuck the landing. The climax and the ensuing confusion almost seemed intentional, as if discouraging you from overanalyzing and asking questions.

Still, at the end of the day, The Third Rule of Time Travel is a fresh and ambitious novel whose risks largely paid off. Despite a few minor stumbles here and there, the story managed to avoid major pitfalls that tend to plague hard science fiction time travel narratives—namely, the type of overly complicated or excessive minutiae that causes much frustration to readers. Overall, it was a worthwhile read that mades me appreciate the subgenre.
