A great read that leaves some loose threads
Format: Hardcover
I knew next to nothing about this book going into it other than that it was a horror novel and that my book club selected it. That’s neither a point in favor of or against the book itself, but it does become relevant in a moment because my lack of background shaped how I approached it to a certain extent. But before we get to that, the basic premise here is that this young couple has moved into a new house. One day while only one of them is home, there’s a knock at the door. This family is there and they say they used to live in the house and want to look around. In the real world, most of us would find that a slightly awkward situation but not an entirely unheard of one. In a horror novel, you know it’s going to set things in motion that probably won’t end well for at least someone involved, and that is indeed the case. But, contrary to immediate expectations, this doesn’t shift into a home invasion story. Instead, it treats us to a bit of slow burn horror as this visiting family seem slightly “wrong” for reasons neither the reader nor characters can put their fingers on, and things ultimately lead in rather unexpected directions, though I won’t spoil too much there. One of the interesting things I noticed quickly is that little interlude chapters throughout the book were punctuated with bits of Morse Code, which I dutifully translated as I read and which slowly began to hint at more of what was going on behind the scenes. That was a nice touch, I thought, but the novel eventually ran even further with that idea, treating us to more substantial codes and ciphers that became increasingly difficult to decrypt or translate. Some eventually became so frustrating that I took to the Internet for aid, whereupon I discovered that to solve some of them, you actually need clues from an alternate reality game which coincided with the book’s publication, but which the novel itself never directly alluded to, so that felt like a bit of a cheat to me, though I was eventually able to gather the information needed to solve the puzzles. Ultimately, I did not find those solutions necessary to understanding or enjoying the book, so it’s not too big a deal. The book itself was engrossing and exciting throughout but left the reader feeling like we’d only just gotten the tiniest taste of a much larger mythology, and I found myself wanting quite a bit more by the end of it, and I mean that in both a good way and a bad way. It’s good because it means I found the book so good I wanted more, but it’s bad because I found the ending left far too many loose threads for my own taste. But if you like a book ambitious enough to risk feeling a bit convoluted and yet with a clear sense that the author always knew exactly what he was doing, I think you’ll like this one. Though it’s far from AS complex, I think it will appeal strongly to fans of House of Leaves. Both thematically and in terms of structure, I noticed certain parallels between those works.

Give it a Go
Format: Hardcover
I was captivated by the storyline from the very beginning. I had read numerous glowing reviews about this book, so I eagerly delved into it, eager to be swept away by the thrilling mystery that lay ahead. While there were a few instances where the chapters felt unnecessarily lengthy, the book was generally exhilarating and suspenseful. Of course, there were some predictable elements, but where's the fun in predicting everything? Overall, I enjoyed the twists and turns of this novel. However, the ending fell short of my expectations (which is a "me" problem). There were a few unanswered questions (perhaps by design), and the ending—well, let's say I wasn't a fan. Nevertheless, the Moris code and the puzzle within one of the DOCs were delightful touches that added depth to the novel.

Confusing in the Best Way—A Chilling, Unforgettable Read
Format: Hardcover
This book completely pulled me in. It’s suspenseful, surreal, and genuinely unsettling in a way that lingers long after you put it down. The story keeps you slightly off-balance the entire time—you’re not quite sure what’s real, what’s not, or where it’s all going… but that’s what makes it so gripping. There were moments where I felt confused, but not in a bad way—it adds to the eerie atmosphere and makes the payoff even more impactful. It’s one of those books that keeps you thinking, piecing things together, and feeling just a little disturbed the whole way through. If you like psychological thrillers that are tense, strange, and a little terrifying, this one absolutely delivers. 5/5—haunting, gripping, and worth the ride.

Be ready to question everything and everyone…
Format: Kindle
We Used to Live Here definitely nails the creeping sense of dread and paranoia throughout the story. I constantly questioned whether Eve was truly unraveling or if she was the only person actually sensing danger, and the added news articles, interviews, and scientific discussions throughout the book made the atmosphere even more unsettling. I also connected with Eve’s struggles surrounding anxiety, people-pleasing, and past religious experiences, which added an emotional layer to the horror for me. That said, the pacing felt super uneven. Most of the story takes place over only a couple of days, but it dragged at times and honestly felt like it would work better as a movie than a book. Things finally picked up around the 70% mark, but the ending left me wanting much more explanation and payoff than we as the readers received. Overall, this was an eerie, anxiety-inducing read with a fantastic atmosphere, even if the execution didn’t fully land for me.

Format: Paperback
I liked the pace, the story and the characters. Sadly I found it at the end a bit confusing. I think the book needed more edition work. Otherway, it is a recommendable book if you want horror with a bit of science fiction. Be advised you'll need to use your imagination to understand certain pasages.
