Plot in a nutshell: an aged pope authorizes a risky mission to free a Chinese bishop from the prison in which he has languished for 30 years. Everything's going just great until The Vatican springs a leak.
This is the first Tom Grace book I've picked up, and - fair warning - I did so because I heard the guy call in on Limbaugh's show. I enjoyed it: I found the Catholic characters very sympathetic, and the general theme about the underground church in China compelling. The action was decent, and the ending satisfying - if rather predictable.
At about 350 pages, this was a very quick read; Tom Clancy would have at least doubled the page count for a similar plot. This is the first major problem with the book: it should have been longer. The short chapters kept you turning pages, but there wasn't enough time to really develop any of the characters, do more than gloss over the many locations we were visiting, or truly build suspense. The characters did not, by and large, begin to escape two dimensions; the dialog often seemed forced; and some of the prose was wince-worthy when the author tried to get fancy with his similes and metaphors. In other words, it suffers from not having been written by Clancy!
Still, that author can only write so much (and even much of his current stuff is being farmed out, I notice), and this is Far from the worst political / military thriller I've picked up, or even finished. Although few political-fic writers are left-wing radicals, it's clear that Grace's worldview is even closer to my own than many of his cohort. I may possibly go back and read one or two of his earlier novels.
