Life in the French Foreign Legion: How to Join and What to Expect When You Get There
I just picked this up off of Amazon last night (the Kindle edition) and am already 20% through it; it's a great read. I have no illusions of joining the FFL, but it's interesting to read what this guy went through during his five-year contract with them (1989-1994).
Looks like a really interesting read!
