I wasn't sure what to expect from this novella. I received it in a book pack bought from Ian Whates excellent website, NewCon Press, but had never heard of Philip Palmer or this book.
It fits a lot into it's 107 pages and I was pleasantly surprised by how good it was. The first half of the book reminded me of David Mitchell's Boneclocks and Slade House, which I'd read a year or so ago and highly rated. The second half goes off an a slightly different tangent than Mitchell's books, but not in a bad way. Whereas Mitchell's books tell how the privileged elite feed off (literally) the ordinary masses, Palmer takes this and adds an alien factor.
If anything, I felt that the end of the novella was a bit rushed, and the story could have been expanded, but I understand the constraints of writing a novella or short story. What I couldn't fault was how well the story flowed and how well written it was. I certainly would be interested in an expansion of this book or a continuance of the story, and will be checking out this author in the future.
