ruthless.com by Tom Clancy and Martin Greenberg is part of the powerplay series.
I was a bit disapointed by this book: the typical tension built up of Clancy’s books is delayed till there are only roughly 30 pages left and there is a lof of (as I felt) unneeded detail with regard to character description.
The book is only 353 pages long. When compared to Rainbow Six or The Bear and Dragon this might be the reason for the late mount of tension.
I can imagine that the detailed descriptions where supposed to clarify each character’s motivation but I only felt bored and found myself skipping ahead more than one time.
