I received an advanced copy from the author and finished about a week ago but wanted to let it set in before I wrote a review. Sometimes my opinion of a book changes a little after I've had some time to reflect on it. As others have noted, this is very similar to Event Horizon, equal parts sci-fi and horror, perhaps leaning a little more toward horror. I'm a big fan of this type of story and there is very little "space horror" out there so if you like this kind of stuff, I would recommend this book. It started a little slow but once once the madness began to ensue, about 100 pages in, I was hooked and really enjoyed the other-dimensional themes that the author explored. It was a unique book, my first by this author, and I look forward to reading his first novel, the Stoker-nominated That Which Should Not Be.
