This is another story in a series about the exploits of the members of the dark Dept 89 team of Germany. This novella moved rapidly along and it was hard to put down for a minute. If you like 21st century international intrigue, this is a story you won't want to miss.

Like the first two books in this series, this one is action packed from the first page. It's fast paced, exciting & very hard to put down! (I only managed that once during the whole book). It's a great change to read something other than how the USA saves the world! The characters are well written, the plot easy to follow & with just the right amount of dialog. I loved it!
