Earlier in the series Jonathan Maberry did an excellent job of coming up with unique threats for each book and finding a way to explain the existence of mythical creatures with "scientific" reasons. This allowed Joe Ledger to exist in a world grounded in modern science and yet battle all kinds of fictional creatures to keep us safe. However, the last book, Dogs of War, re-used a lot of threats from earlier in the series and when this book started with pretty much the exact scene from the start of a prior book I instantly knew I was in for more of the same.
