This is an OK little book--only 160 pages--written by an American about the experiences of his German father-in-law (Karl Roth) on the Eastern Front during WWII. Actually, Roth seems to have been rather tight-lipped with his stories, so there is actually very little first-hand information about his experiences...rather, the author has spoken with as many members of Roth's unit as possible and done some research to find out about what the unit did, and about Roth's role.
Roth was in a panzer maintenance unit during the war. so there are rather few combat stories in the book; rather it mainly consists of a potted history of the war on the Eastern Front, along with some reminisces by Roth's colleagues and his family, usually about topics such as training, leave, etc.
Generally not a bad book, but not really much meat here.
