This is a story of an American writer turned reluctant spy during Germany's invasion of Greece during WWII. It is also the first book by Leon Uris that I've read.
The writing was well done - well paced, good character development (mostly) and tension throughout. The Greek/British Underground was busy pulling a fast one on the German invaders, even as the author was giving the reader misdirection. :)
One thing that annoyed me - a typical pet peeve - is that there is a love story where by the 5th day after meeting, they use pet names (honey, darling) and by the 9th, they've professed their love. Maybe I'm just not a believer in love at first sight....
I would rate this a 3.5 due to the good storytelling and the tension throughout.
