The Unseen III: Final Slash

Rate this book
"Bryan Smith is one of my favorite authors. His books are dreamy, weird, gory, thrilling, funny, sad, scary . . . all of it. If you like horror, you should already be reading him."
--Judith Sonnet, author of Our Sarnath

In her own world, Allie Cook was a respected horror filmmaker who had it all—a flourishing career and critical acclaim as the “Queen of Horror”, and a happy marriage to the love of her life. Then it all came crashing down when her doppelganger from another reality, the far more troubled Allison Cook, stole Allie’s life out from under her.

Five years after the events of THE UNSEEN II, Allie sits on death row in another world, counting down the final hours until her execution for murders Allison committed. All hope seems lost until she receives an unexpected chance to reclaim the life that was taken from her.

Allie and Allison are mirror images of each other. So much alike, yet so very different. In the end, only one can survive, but which one will it be?

Allison got a second chance at life after switching places with Allie, but she has quickly wreaked havoc and threw her new life and reputation in the fire. Allie is on death row for crimes she didn’t commit when an unexpected event provides her with the perfect opportunity to seek revenge on Allison.

We get to see a lot of inter-dimensional travel and some answers as to how it’s possible.

Freya and Alyssa were interesting additions to the story.

We don’t really get to see the Visitor very much or get any kind of conclusion on his motive. He just does his own thing as an inter-dimensional parasite who feeds off of people and their emotions.

I really enjoyed the scene in the field when all hope seemed lost for Allison.

The big part of this book was Allie and Allison somehow reuniting, which does eventually happen. But I feel like not enough time was spent with them actually together after everything they have been through and the anger and hostility they had for one another. How they part ways was also really surprising.

The writing was still excellent. There were tense scenes, suspense and a little bit of death and gore. I enjoyed the series for the most part, but I do feel this book took a bit of a plot turn and didn’t wrap up as nicely as the first two books. There was also a lot of convenient events that made me a bit weary and shake my head a little bit. The first half was great, but the second half was a bit of a head scratcher. The ending was a bit of a let down, only because I feel like this person didn’t at all deserve what they got and it was left very open. Still a very interesting concept for a series and I’m glad I read it!

Bryan Smith's contribution to the extreme horror/splatterpunk genres always feel like to me like crazy but insane horror movies in book form and I love his work because of that. The Unseen is one of my favorite stories and concepts from this writer, such an ingenious idea that is a lovely homage to 80s slashers, while also playing around with the multiverse, an idea that is popular at the moment across the board. The announcement of this third book surprised me greatly, especially given my love for the first two books and the second book's ending.

Allison Cook has replaced Allie Cook's existence. She has now become a famous film-director who is renowned for producing a ton of amazing films. Unfortunately, she knows nothing about making films and so has ruined not only her dreams but the life of someone she trapped back in her own universe. Allie Cook is on death row; she's about to receive the lethal injection when an unexpected saviour arrives. Allie Cook is on a mission to restore her life and to stop Allison Cook from causing more damage back in her universe, but the journey back is going to be quite the ride.

Bryan Smith's concluding novel in The Unseen Trilogy is by far the most insane installment in the entire series, this is a book that explores the multiverse angle more so than the previous ones and gives us a glimpse into the lives of people like Allison Cook in their other universes. Mostly, this novel is set within a horror convention in Allie Cook's universe, but it takes time to explore Allie's journey back home. This is a fast-paced bloody read that concludes with a really satisfying finale.

This is a very dramatic concluding novel with a lot of blood, insane ideas and a heartbreaking finale that will have you screaming at the unfairness of it all.

Overall: Final Slash is a brilliant concluding installment to an outstanding trilogy.

Not as fun as the first book in this series. The first sequel wasn’t as good and dragged in places but this final part of this supposed trilogy felt phoned in. Flimsy plot and felt like Bryan Smith had abandoned some of the rules of his Visitor mythos.

excellent ending

This book, imo is the best of the three. It was exciting, entertaining, and kept me interested throughout. I made the mistake of starting it late on a Sunday night…

I thought The Unseen II wrapped things up — that last "Twilight Zone" twist felt like the ending. But when The Unseen III popped up in my Continue the Series recs, I jumped on it.

If you haven’t read The Unseen and The Unseen II, stop now. This is a single-arc trilogy — no skipping around. You need the first two for this one to land.

Five years have passed, and Allison is… well, she’s Allison. You can change your universe, but you can’t outrun who you really are. What starts as a clean slate turns into a slow-motion crash — career destroyed, relationships burned, the bottle always within reach. Meanwhile, the other Allison — Allie — sits on death row, still paying the price for crimes she didn’t commit.

Bryan Smith didn't feel like leaving it like that so, he does what any good writer does, he spares Allie from the death chamber and gives her the ability to reclaim her life back. Her heart is still strong, her morals and convictions put her in the right. Allison has made a mess of her life, and Allie wants it back, but first she needs to get back to her own universe, and find Allison before it's too late to save either of them.

I don't need to warn readers that this is like the others where expectations will be subverted...
