Chris-
I've read some reviews and they alternate between ecstasy and "mind-numbingly boring"; though to be fair, more on the first side. I refuse to read any war (or spy) books whatsoever so not going there!
Why did you not give up? Was it because, like "Captain Corelli's Mandolin", everyone said it starts slowly, but it's worth pursuing (as that one certainly was), or because you thought "It must get better"? I read between 4 and 5 novels most weeks and if I am not engaged by about page 75 I give up.
I'm currently reading "Breaths of Suspicion" by Roy Lewis and it's getting near page 75......
