Happy Tuesday, bibliophiles!
We’re keeping up my sequel streak for the time being, so it seems. The difference between this and The Heart of the World is that I had no idea that The Darkness Outside Us, one of my favorite books of 2021, was even getting a sequel in the first place. That novel rocked my world—it really enraptured me in a way that not a whole lot of books ever have. But it was beautiful as a standalone—it had about as satisfying of an ending as you could ask for. So I was teetering towards hesitantly optimistic when I heard about The Brightness Outside Us, but in the end, I’m so glad I took the gamble; this novel is a different kind of twisty than its predecessor, but it’s worth taking the leap.
Enjoy this week’s review!
Now, tread lightly! This review contains spoilers for book one, The Darkness Outside Us. If you haven’t read it and intend on doing so, read at your own risk!

The Brightness Between Us (The Darkness Outside Us, #2)
In the 24th century, Ambrose Cusk is on the cusp of the greatest space mission mankind has ever embarked on. After losing his sister Minerva in a troubled gambit outside of the solar system, Ambrose is set to cross the universe itself in order to save her. But when he discovers that he won’t be on the ship—only clones of himself—he is determined to get to the bottom of what his true mission is—and what really happened to Minerva.
30,000 years in the future, the final clones of Ambrose and Kodiak have grown from the teenage clones they once were into fathers of two children. Owl and Yarrow live a peaceful but sheltered existence on the surface of Minerva. Owl yearns to learn what the rest of the planet holds, but her parents are keen on keeping her safe. But when her brother Yarrow begins acting strangely, the family suspects that a stranger thousands of years in the past may have sabotaged their mission.

It didn’t even cross my mind that The Darkness Outside Us would have a sequel. I went into this novel with trepidation—how do you follow up a novel as twisty, complex, and heartwrenchingly beautiful as The Darkness Outside Us? By splitting the novel in two, as it turns out. I didn’t think that The Darkness Outside Us needed a sequel, but nonetheless, I’m glad I stuck around to see the result—of course Eliot Schrefer would have something fascinating up his sleeve.
The Brightness Between Us reminds me of how much I love a good “space colony gone wrong” story. As I said, I didn’t even think about The Darkness Outside Us getting a sequel, but this novel has the perfect setup for precisely this kind of plot. I should have trusted Schrefer from the start, given how masterful book one was, but wow, the Minerva plot amazed me! There was so much solid, hard sci-fi put into the terrain, climate, and wildlife of Minerva, and Schrefer did an excellent job of keeping the reader in the dark just enough to make everything suspenseful, even when the mysterious bones that Owl digs up in her exoplanet yard only turn out to be from a duck. From the research behind the wildlife, the weather, and the atmosphere, no stone was left unturned, each one its own Chekhov’s gun waiting to fire.
Although Owl wasn’t my favorite protagonist, she fits perfectly for the environment she’s in. Every “space colony gone wrong” needs a character who questions everything; there is always some part of the planet that has been unexplored, and someone needs to be curious and daring enough to want to discover what’s on the other side of the world. It can be even more effective when that character is a child; children are naturally curious, making it more than simply questioning authority—the authority is often their parental figures, and the excuses of them hiding things “for their safety” feel more tangible. Fifteen-year-old Owl was naturally curious, but also paired with her more obedient (at first) brother, Yarrow, giving her more resentment towards her parents. She wasn’t as likeable as Ambrose or Kodiak (I loved seeing them become parents), but they had the home field advantage of book one. But I can recognize when a character is perfect for the plot they’re in, and Owl was the perfect match for the plot of The Brightness Between Us.
After the pummeling of gut-wrenching twists that we call The Darkness Outside Us, the sequel was going to have to pull off a miracle to follow it up in terms of plot. The main twist was so earth-shattering that I thought it would be impossible to come up with anything better. I remain correct—I don’t think anyone, much less Schrefer, could come up with a twist that could top book one. But the main twist that we do have was excellent enough to propel me to finish the book in one sitting—just like The Darkness Outside Us! (The difference is that it was at a reasonable hour this time. I’ve matured since 2021, I promise.) Not only is this duology a love story 30,000 years in the making—it’s a conspiracy 30,000 years in the making! I loved the twist that Devon manipulated the frozen fetuses to develop violently aggressive traits as they grew—it gave even more stakes to an already gripping plot, and it made the days of present future half of the novel gripping as well. It gave the “space colony gone wrong” side of The Brightness Outside Us a truly unique twist—sabotage from 30,000 years in the past, and two versions of the main characters communicating across time to thwart it.
All this talk about the Minerva plot, and I haven’t even touched on the “present-day” Ambrose and Kodiak…oops. I don’t have a favorite child, I swear. The worldbuilding in this half of The Brightness Outside Us was my favorite part; getting a glimpse into the forgotten world that we only knew about in whispers in book one was fascinating. Schrefer’s vision of a world divided into a corporate hellscape of excess and a corporate hellscape of rigidity was one that was mapped out just as vividly as the alien world of Minerva. You really do see how it is that Ambrose and Kodiak got to be how they were at the start of book one. In terms of character development, it did tend to feel like listening to a broken record after book one, but that’s my only minor nitpick—Schrefer made sure that they had startlingly different—and almost as emotional—arcs as their clone counterparts in The Darkness Outside Us. Devon was a fascinating, slippery antagonist, and his sabotage was one of my favorite parts of the novel to witness unfolding.
All in all, a sequel that had a Herculean task to live up to its predecessor, but delivered a miracle in spite of the odds—just like Ambrose and Kodiak. 5 stars!
The Brightness Between Us is the second book in The Darkness Outside Us series, preceded by The Darkness Outside Us. Eliot Schrefer has also written several other books for children and young adults, including the Ape Quartet (Endangered, Threatened, Rescued, and Orphaned), The Lost Rainforest series (Mez’s Magic, Gogi’s Gambit, and Rumi’s Riddle), Queer Ducks (And Other Animals): The Natural World of Animal Sexuality, and many others.
