Probably the least gripping book of his 4 book series, but maybe the most interesting. Not many bullets fly, but Burgett is in at the kill of Nazi Germany. Big picture history in the making. He sees first hand the horrors of the Concentration Camps, he makes it to the Eagles Nest, he participates in the dismantling of the German war machine... and he makes it home in one piece, something many of his companions did not.
I also feel it worth noting that Burgett's writing skills improved over the course of the books. Book One seemed very detached and I never really got a feeling for the troopers he served with or even, sometimes, a clear idea what was going on. By Book Four he is much more adept at fleshing out scenes and characters. It was interesting seeing this element of his story progress.
