An excellent title is The Book Thief by Markus Zusak. Narrated by Death, it is the story of Liesel Meminger, who is growing up in Nazi Germany. Liesel's gift of storytelling helps sustain her family and the Jewish man hiding in the basement. This book will make you laugh and cry, but it will not depress you. The pain contained is bearable and the ending, consoling. A must read for teens and adults.
