Query: True or not, an excellent read

I am an avid reader of non-fiction adventure/survival stories and found this book to be well written and hard to put down. There is much controversy about whether it is fact or fiction yet I found the story to be plausible and fascinating.Slavomir Rawicz is taken prison in World War II, subjected to horrendous conditions, and escapes with some other prisoners. Then the story takes off as it describes their 4000 mile trek over mountains and across desert.True or not, it is an excellent read.For other books that I found gripping and well worth reading, see my other reviews or my listmania list.
