My husband and I are trying to expand our classic lit library. We have a few (I won't bother to list them all as it would be fairly long and I need to fold laundry) but we would like to add to our collection.
My husband will have a good amount of free time to read when he is overseas and I want to send him a 2 new books about every two to four weeks, one theological one that is more "fun." So, "Heart of Darkness" or other really sad/melancholy/dark books won't be a good idea. You can list them, just please preface that they are dark so they can be read in about 2 years after he is back and we are "happier."

Last time he was deployed he was desperate enough for reading material that he actually read a "mens magazine," I think it was FHM or some other mag like that. Not to insult those that read those mags, but when you are surrounded by cussing and toilet humor 24/7 you want something a little more mentally stimulating. And it would be nice if he doesn't have to have a cussing jar when he gets home

The cussing is in his control, but having books to take you out of your surroundings helps tremendously.
And if you list a book that has many various printings, (I.E the Brothers K has many versions in English, some better or worse than others) if you could list your favorite one that would be nice.
Theological book recommendations are welcome. He is taking Philokalia volumes 1-4 with him and his bible. He can't take a great deal of books with him since he is limited to a certain poundage of stuff. I can ship him as much as I want, he just can't take it with him.
