Great mystery concept, poor paper quality
Format: Paperback
Love the concept and the book but the quality of the paper and cover just really disappoints me. Because you have to flip back and forth you’re going to be handling this a lot. I had the book at the pool and the edge got wet and the cover just delaminated and came apart. I have really enjoyed the complexity of this mystery and cannot wait to find out who the killer is!

Perfect for Mystery Lovers and Overthinkers
Format: Paperback, Format: Paperback
I picked this up thinking it would be a quick little puzzle book and ended up way more invested than I expected. The entire concept is basically solving a murder mystery through elimination clues, and it honestly feels like a mix between Clue, logic puzzles, and a detective game you can do by yourself. Each page gives you clues about who the killer is NOT, so you slowly narrow down the suspects by crossing out names based on things like syllables, vowels, letters in their name, etc. Some clues are super straightforward and others make you stop and really think. It’s surprisingly addicting once you get into it. What I like most is that it actually keeps your brain busy for a long time. This is not one of those puzzle books you finish in an hour and forget about. I’ve been working through it slowly because there are SO many pages and clues. It’s honestly kind of funny how serious I got trying to figure it out. The layout is easy to follow, the concept is original, and it’s a great option if you like mystery games, logic puzzles, escape rooms, or anything detective-related. I could also see this being really fun to bring on a trip or keep around for downtime instead of scrolling on your phone. Definitely worth it if you enjoy interactive mystery books and want something different from the usual word searches or crossword puzzles.

Better Than the Movie
Format: Hardcover, Format: Hardcover
I picked up Remarkably Bright Creatures after hearing so much buzz about it, and it absolutely lived up to the hype. This is one of those rare books that is heartfelt, funny, emotional, and completely unique all at the same time. The characters feel real and layered, and the story unfolds in such a thoughtful, satisfying way. Marcellus the octopus completely steals the show. I didn’t expect to become so attached to an octopus, but his chapters were easily my favorite part of the book. They added humor, wisdom, and so much heart to the story. If you’ve already seen the movie adaptation but haven’t read the book yet, you absolutely should. The book goes so much deeper emotionally and gives so much more background and connection between the characters. I enjoyed the movie, but the book made me care about the story on a completely different level. The writing is approachable and easy to get into, but it still leaves a lasting impact. This would make a great book club pick or gift for anyone who enjoys character-driven stories with warmth and emotional depth.

Great story and characters
Format: Kindle
I had to see what all the hype was about and after seeing the trailer on Netflix I knew I had to read the book before I watched the movie. I have to say, this was one of the better books I've read so far this year. It's not a fast paced read but it held my interest the entire time. The characters are very well developed and I really grew to like Tova and Cameron, of course Marcellus is the star of the show and is as witty as they come. If you're looking for a good read I highly recommend this one. The octopus is a difficult creature to care for so I sincerely hope the "octopus tank craze" doesn't start over this like the "clownfish tank craze" did when Finding Nemo came out. Leave it to the expert level saltwater hobbyist to care for them or better yet, leave them in the ocean. I have to mention too that this is the author's debut novel and for a debut novel it's very impressive, I'll look for others from her in the future.

A Remarkable Book--I Want More Like It!
Format: Kindle
I stumbled on Remarkably Bright Creatures among my recommendations. As often happens, the premise intrigued me enough to read it even though I didn't know the author. Well, if Shelby Van Pelt often writes like this, I definitely want more of her books. The friendship between Tova the aquarium cleaning lady and Marcellus the giant Pacific octopus is a definite selling point in this book. It's a great twist on the "A Kid and Their X" trope (the kind of thing you see in stuff like Where the Red Fern Grows, Old Yeller, Free Willy, and so forth). This one, I am pleased to report, is far less cheesy and saccharine. Tova is a multifaceted character whose life may seem small in her estimation, and probably is if we go by what is a "normal" life in a small seaside town. Yet that life has been stuffed with complex emotions, unanswered questions, and a longing for "more" that I think everybody can relate to. At least, I certainly could. As for Marcellus, he's multifaceted, too. A part of me did stick with his point of view, and story, because it is a story of a "remarkably bright," underestimated creature trapped and controlled in a world he doesn't understand. I have cerebral palsy and was diagnosed as level 1 autistic this spring; I'm still looking back and trying to heal from a lot of the latter's implications. So in a visceral way, yeah. I'm not a captive animal or mistreated, but I understood how Marcellus felt. What I liked even better about his story though, is that Marcellus' story doesn't stop there. Marcellus actually has a life and a history that Shelby Van Pelt, Tova, Cameron, and other characters dig into. He's not just a captive yearning for freedom and mourning lost opportunities, as often happens with similar stories. He makes wry, witty, yet quiet, non-snarky observations about humans. He cares deeply for Tova because she took time to know him as a "person," but also because she's the only human who has ever stopped long enough for Marcellus to know as a real "person." Marcellus gets to be the conduit of real revelation and change for people inside and outside his world. That's amazing, and frankly, it's a lot more than many human characters get. Remarkably Bright Creatures couldn't succeed with just Tova or Marcellus though, or at least not as well as it did, I think. The other characters pop off the page as well. Cameron is my favorite, precisely because I didn't expect to like him at first. By his own admission, he comes off as a burnout and a loser, and I admit, that's how I saw him to begin with. But as with Tova and Marcellus, Cameron is hiding a lot of layers, a lot of depth. He's got a great heart, but he's still a typical, kinda clueless 30-year-old guy (and I'm still a 30-something so I say that tongue in cheek). He's vulnerable but not pitiful; he plays the victim sometimes, but then he gets mad at being called out on that and wants to do better. He struggles and is a burnout, but he's got good, solid friends and some real interests and potential. In other words, I got really into his arc, especially once Tova, Marcellus, and even Ethan got involved. As for Ethan, he's unexpectedly cool, as well. I admit some brownie points with him, as I love all things Scottish or Irish and he is of Scottish descent. But I also didn't expect a shopkeeper in his '70s with a gruff edge to be a Grateful Dead fan or to get along so well with a neat and tidy, tiny Swedish aquarium cleaner, so brownie points on plot and character there. In fact, Ethan's role in the story, in particular, went all kinds of unexpected places, so without spoiling anything, I'll tell you to keep an eye on it. Finally, Shelby wins some extra brownie points for a lot of the "little" things that "pop" out at me when reading a book like this one. For instance, I love cats and love the reluctant yet affectionate relationship Tova develops with a stray cat. I love Marcellus' Collection and the pride and care he takes in it. I love and felt some heartbreak over Tova's reminiscing about the attic playroom that never got to be a playroom. But I think the thing I loved most about Remarkably Bright Creatures is how remarkable Shelby showed readers humans--and creatures--can be, without getting heavy-handed or cheesy. There are some romances here, so to speak, but this is a relationship novel, and those are, have been for the past several years, some of my favorite ones. There is some language here, so caveat emptor if that's not your thing. From a writer's perspective, I also wondered how much some threads or characters were actually needed. For instance, looking back, I understand why Tova had a brother, but I'm unsure how much he furthered the plot. Similarly, I understand the roles of Avery and Marco but again, am unsure how much they furthered the plot. Also, I almost hate to say it, and I could be wrong about this. After all, I know about as much concerning octopi as the average person who watches Jeopardy (which I do). But while Marcellus' plot thread is great, and while I definitely understand suspension of disbelief, I did wonder along with Cameron how much those boundaries were pushed. I mean, I buy Marcellus getting out of his tank, and with the right Collection items, I guess Tova and Cameron could've figured out whatever they needed to know. But...there's a logical shard of me that isn't quite sure she buys how everything lined up, I guess. All that aside though, Remarkably Bright Creatures is still a remarkable book. As often happens, I'm now eager to find more like it. And yes, it does get a hearty recommendation. At the very least, I'll want to take closer looks next time I go to an aquarium.
