This is by Ariel Sullivan and is slated to come out March 24, 2026. 

I enjoyed Conform, so I was interested when I saw this ARC. The book is pre-dystopian in a way, since it is supposed to set up the dystopian world we see in Conform. That being said, you do not need to have read Conform for this book to make sense. 

The prequel follows FMC Sasha Cadell, a former medic who’s now doing menial labor to cope with the losses and hardships she’s had to deal with following the nuclear war that destroyed much of humanity. Sasha is basically just trying to survive. As a character, she is smart and capable, but has huge walls up. 

MMC, Tristian Hayes is genuinely a good guy. Strong, resilient, loyal, he was very likable. It did take me a bit to realize his name wasn’t Tristan though. He is the leader of an exploratory unit who is looking “above” for supplies or anything that can help Haven, the world below. He believes a medic is necessary for their team to continue its work, and maneuvers Sasha onto his unit. She does not want to be there. 

The romance between them was pretty well done. It felt slow paced and full of yearning, but also dissatisfying at points in the beginning because FMC was (understandably) in her own way for much of it. You really do root for them though. 

Other characters: this book is an example of an excellent and believable found family. I liked the side characters a lot. You got enough of a glimpse into each of their lives that you felt like you knew them as well. The only thing was that at times it could be confusing because the author referred to them interchangeably by first name, last name, and “call sign”/nickname. 

Plot/pacing: I really enjoyed the political and exploratory nature of the plot. She did a good job building the world and describing the different sectors and societal rules. The pacing though felt a little off in the beginning; it was a touch slow, and some moments felt repetitive. Regardless, I disregarded it because I was pretty engaged in the book. 

That being said, I expected it to have more of a tie in to Conform. Yes, it takes place before the Conform world does, but the end of it does not clearly delineate how Conform itself begins. The book also ends on a sort of cliffhanger, which surprised me. I was expecting it to wrap up, but I’ve just read the authors instagram stating there are three trilogies planned for this world, so now we have the first books of two of them. That’s good, because I really liked these characters — they felt much more compelling than the ones in Conform and I was not ready to leave the when the book abruptly ended. 

I liked Conform fine, but I do think this was the better story. The characters also felt and dealt with more raw emotions and experiences to me. I highly recommend this book, especially if you liked Conform. 

If you’ve also read Beneath (or if you do read it), please feel free to share your theories here (just make sure to mark spoilers with the spoiler tag)! I’m eager to discuss the book with people!
