Hi Hijo,
There are many books i'd have wanted to read. I have a Recommended reading list at the back of a book given me (Disciplines of a Godly Woman), many of which i havent read, but which i would too if i can!
Heres some fiction and nonfiction, missionary bios, devotional studies and helps. See if you find any interesting. Btw not sure what you mean with youth books, but when i was studying, my father recommended we read biographies.
