The Queen Esther Pamphlet is an excellent overview of the story of Queen Esther in the Bible.
Esther's story asks the important question: Where is God when things go wrong?
It's easy to characterize Queen Esther as the lucky orphan girl who won the heart of the king. But in reality, she was a young woman with a tragic background and dangerous secret that could cost her life and the lives of her family. She was married to King Ahasuerus (King Xerxes) who destroyed peoples' lives on a whim and had a history of killing people close to him. Worse still, the king's favorite counselor and chief advisor, Haman, was a mortal enemy of Esther and Mordecai's family.
