I don't usually read these types of books but someone highly recommended it...
The Forgotten Soldier - read the reviews
Anyone who wants to come as close to experiencing war from a book this would be the one.
I have found after reading this how ridiculous I sound when I think I cannot fast like I want, or cannot tolerate and have the patience for something. This book has really helped me realize how life is so very easy for me, but most of all, how undisciplined I am.
I think anyone who likes philoshophy, such as Seraphim Reeves, would also find this a mountain to reflect on.
