I suggest that you youself should re-read the story of Esther, perhaps accompanied with a good commentary or guide.
I find it to be an inspiring example of how to conduct oneself with honor and tenacity in times of great difficulty and peril, and a great example for both men and women of God.
As for the innacuracy part - it’s in the Bible, and it’s there for a reason. Personally, that’s all I need.
I agree with you. Charles Swindoll has an excellent book about Esther in his “Great Lives from God’s Word” series. It shows that even though God isn’t really mentioned in it, it is obvious to those who can see that His fingerprints are all over the place.
The Book of Esther is so inspiring. One of my favorite books in the Bible.
