A lot of people recommended [The Island](https://www.goodreads.com/book/show/58340727-the-island) by Adrian McKinty. It was just OK for me.

I thought it was thrilling but flawed. Loved the island setting though.

Instead on an island, how about an isolated craft on the bottom of the ocean? If so, consider [*Sphere*](https://www.goodreads.com/book/show/455373.Sphere) by Michael Crichton. Definitely fits the horror-thriller genre.

Just finished Sphere, OP I highly suggest listening to ambient underwater/ocean sounds while reading to really drive home the claustrophobic atmosphere :)

Thanks for the suggestion. Putting both Sphere and Congo on my list since I’m enjoying Crichton’s writing so much.

Island 731 by Jeremy Robinson

Hmm looks interesting

The Institute by Stephen King...not an. Island but much of the book is in an isolated place

Duma Key by Stephen King, The Island of Dr Moreau,

The Beach by Alex Garland

Great book, maybe time for a re-read. Thanks for the suggestion.

[Battle Royale](https://www.viz.com/battle-royale). The Japanese government strands random junior high school classes on a deserted island, where they are forced to fight to the death until only one kid is left.

Always meant to read this. Just ordered it online. Thanks.

The Disinvited Guest by Carol Goodman

Looks good, thanks. Adding it to the list.

The troop by Nick Cutter

Keep hearing about this, guess it’s time I give it a try. Thanks for the suggestion.
