Happy Tuesday, bibliophiles!
First book review of 2025, and so far, the best book I’ve read this month! Granted, we’re only a week into the month, but it still counts for something, right? loved Mooncakes, which Wendy Xu illustrated, but I had no idea until recently that she had published a solo graphic novel—and a sci-fi one! What resulted was an incredibly emotional read to start the year off with: robot romance and explorations of how relationships make the universe work.
Enjoy this week’s review!

The Infinity Particle – Wendy Xu
Clementine Chang is headed for Mars. In the distant future, it’s a place of peace and industry, and it’s precisely the place that Clem wants to start her new life. A clever inventor, Clem has a knack for working with AI. She hopes to continue her education under Dr. Marcella Lin, a legendary AI engineer who inspired her work. But Dr. Lin is not what she seems—and she’s hiding a secret from the scientific world: a lifelike, humanoid AI that she refers to as her son. His name is Kye, and he yearns for a life outside of the one that Dr. Lin programmed for him. As Clem gets acquainted with him, she discovers that Dr. Lin’s intentions in making him were not as noble as she once thought—and that she may be falling in love with her former hero’s creation.

TW/CW: emotional abuse (past/present)
You know me. I’m a sucker for a good Frankenstein story. Oh, so you brought a conscious being into existence, expected it to be completely obedient to you and your whims, and didn’t expect anything to go wrong? Surely this will not have a domino effect of consequences…
That being said, The Infinity Particle isn’t just a Frankenstein story. We’ve been inundated with stories about AI and the ethics of giving robots human-like consciousnesses since day one of sci-fi’s conception (back to Frankenstein), but The Infinity Particle does what many of those stories try and fail to do: make the story human. It weaves both engineering and the complicated legacies of familial trauma into a story that is ultimately about relationships: that of parents and children, but also of young lovers. It’s a story of breaking cycles and of forging something newer and better out of their ashes. All of it is worth your time.
Wendy Xu’s vision of Mars in the distant future is one that I want to live in, which isn’t something I often say about sci-fi novels. The world of The Infinity Particle is a cozy, comforting one. In spite of the more emotional moments of the story, Xu’s setting is one you can get lost in. Rendered in a pastel color palette that’s easy on the eyes, it’s a world full of greenhouses, cafés, and cobblestone paths. Here, Mars is the perfect place for a museum date—except here, the museum features all manner of robots from bygone centuries. Although there are ethical conflicts with some of the AIs (this forms the central conflict of the novel), none of Xu’s AIs are malicious creatures—they’re all in the form of cuddly cats or owls, and in the case of Clem’s custom companion, a cat-moth hybrid. (SENA!! WE LOVE SENA!!) It’s a world I was eager to escape to, and one that I could dwell in forever.
Clem’s motivations were part of what made this story stand out. As she begins to dig deeper into Dr. Lin’s true motives for creating Kye, the way her former hero treats her AI creation begins to mirror how she was treated as a child; the emotional abuse from her mother is very similar to the emotional abuse by Dr. Lin to Kye. The Infinity Particle is a fantastic example of how very far-fetched, sci-fi concept can be used as incredibly emotional metaphors. We have Clem, who is a clone of her mother and was raised to live out the dreams that her mother could not, and Kye, an AI made to replace Dr. Lin’s son and live out her fantasies. Admittedly, the clone part was very on the nose, but the way that Xu delivered with care, giving The Infinity Particle an undeniable heart. In part, The Infinity Particle is a story of how trauma always echoes into the present, and how it can create ripples that both tear apart and rebuild relationships with others.
That shared trauma is part of what made the romance between Clem and Kye one that I was rooting for from page 1. Not only were they the most adorable couple (museum dates! Philosophical conversations in greenhouses!), their shared connection allowed them to help each other in ways that made the relationship blossom. Clem had experience with having to escape from the same kind of emotional abuse that Kye was undergoing, and as they realized that connection, their relationship deepened. However, it wasn’t just that aspect that made their relationship so lovable. Their chemistry was some of the best I’ve read in a YA novel in a long time—they were both such curious and sensitive people, and that combined curiosity not only drove the plot, but the course of their romance. Every shared moment was sweet, but never saccharine—The Infinity Particle was just a warm hug (and a kiss on the cheek) in so many ways, this being one of the most prominent.
However, even though Dr. Lin was objectively in the wrong, I appreciated the way that The Infinity Particle humanized her; never once were her actions condoned, but in the end, she wasn’t a purely evil person—she was a person who slipped so far into grief that she failed to realize how she was treating those around her. She did horrible things that could not be undone, but she was also capable of healing. It’s an incredibly difficult line to toe between acknowledging a character’s humanity and acknowledging that their actions were inexcusable; most media gets it wrong (I am looking directly at Encanto), but in the short time that was given to this plot, Xu did a graceful job of hitting that balance. Dr. Lin did some unspeakably terrible things, but deep down, she is still human. My one (minor) complaint is that this was squeezed into the end and didn’t have as much time to develop as some other parts of the novel, but it was executed thoughtfully nonetheless.
And the epilogue…hnnnnnnnngh do I love a good “the fabric of the universe is made up of love” story AUUUUUUUUGH
All in all, a heartwarming, sensitive, and thoughtful story of love, robots, and what it means to have—and to want—a mind and a life of your own. 4.5 stars!
The Infinity Particle is a standalone, but Wendy Xu is also the co-creator of Mooncakes and the creator of Tidesong.
