The premise is interesting: what would happen if vampires got onto a submarine? The execution was… not as interesting. Opportunities to build dread were dulled by stale turns of phrase. No kidding, one paragraph included the phrase “it will work; it HAS to work!” and was immediately followed up with “it was their last, best hope.” I don’t usually write negative reviews, but this book demands one. I’m thankful this was a free selection, or else I’d be asking for a credit back.
