For a long time this book was it for the Teddy London series: the final volume. "Robert Morgan" (aka CJ Henderson) was clearly trying to build up to a big climax for the series...but this book misfired rather badly. Part of the problem, I think, may have been that Henderson had written 6 novels in this series in about 3 years; unless you're planning carefully and mapping things out rigorously, it's just difficult to maintain that volume of output and keep it all fresh, new, and interesting. So this book contains _a lot_ of recycled ideas (and characters) from several of the previous novels in the series.
The idea of a bunch of vampire controlling over 200 nuclear weapons is a potentially great idea, but it ultimately fizzles. (HERE'S A SPOILER: FOR THE LOVE OF ALL THAT'S DARK AND GRUESOME, LOOK AWAY NOW!) The new character, Swartz, that Henderson introduces is sacrificed rather uselessly a long time before the climax is even approached. It's like Henderson was tired and just wishing to drop tis to write himself into new characters and situations (as he probably was).
This book is still necessary to reach the much later final 2 volumes of this series, but try not to fall asleep while you read this one.
