Flynn’s prose is sparse, but her messages are powerful ... As the story grows more complex, it’s a thought experiment come to life: what would it be like to meet yourself from five years ago? The characters are well-imagined, but the most impressive is Gabe, the spunky, aggressive, grieving girl who we watch grow up over the span of the 20-year arc. She is angry about the virus, angry about being alone, angry that she’s angry. But it’s all justified, and I found myself rooting for her anger and her distrust of even those closest to her. Flynn has done wonders with Gabe’s character, allowing space and time for a girl’s anger to land and be felt. It’s through Gabe’s eyes that we’re most led to question the morality of this world ... The beginning of the novel takes off with some speed, but it sags a bit in the middle. We are meant to feel the jolt of each chapter’s transition to a new character...but it takes some effort to keep up with the crossing timelines and narrative arcs. By the end third, however, there is a charge and a tension that keeps you turning the pages, questioning who is a companion and who is still fully human. The differences begin to dwindle to a point where the reality and the theory blend in a masterful stroke ... Though a quality dystopian science-fiction novel, The Companions’ most compelling aspect is its commentary on the advancement of technology and the root of what powers humanity at its core. It’s an engaging debut with both speculative and literary gems, one we should read and think about now more than ever.

While the worldbuilding might not be robust enough for some sf fans, the strength of this first novel is in the writing and nuanced characters. Through the experiences of people who might no longer be considered fully human, the author thoughtfully explores the nature of humanity.

In a dystopian California paralyzed by quarantine...readers watch characters struggle with fascinating questions of loss and memory. What does it mean to be alive—to be human, to be real? And what is the cost of remembering what it was like to die? Flynn tells an emotive, mesmerizing speculative story in her excellent debut.

... a great concept that works well initially, but the interwoven strands start to fray not long into the novel. While Lilac is initially presented as the central character, her importance wanes quickly. This isn’t necessarily a bad thing — this kind of narrative switcheroo has worked wonderfully in other books. Here, though, it feels unwieldy, especially as the additional voices threaten to crowd Lilac out. This is made worse by the monochromatic presentation of these viewpoint characters; you could swap out their dialogue or inner thoughts seamlessly ... As with the onslaught of characters, this effort feels like too much crammed into a small space. There are a lot of good intentions, but the execution is jumbled. While Ms. Flynn’s writing often feels like it’s trying to rush you to the next chapter, it really shines when the plot slows down. It succeeds most in the small moments. This is especially true for the quietly sad ending, which feels perfect.

Told by eight voices over the course of 20 years, the overly busy narrative often threatens to overwhelm Lilac’s story. But by the end, Flynn’s vibrant characters movingly answer the oft-asked question, 'What does it mean to be human?' This will satisfy fans of literary and science fiction alike.

Flynn’s characterization is strong throughout, but Gabe is particularly well-drawn. At first, she’s angry, grief-stricken, stubborn, and unwilling to show weakness. Her emotional journey throughout the novel feels absolutely earned. In the midst of a character-driven narrative, Flynn’s simple and evocative writing shines ... Though the plot sometimes feels too convenient, the novel raises important questions about humanity ... A suspenseful, introspective debut.
