She

She (1886) by Henry Rider Haggard

The title character is Ayesha, She Who Must Be Obeyed.

Ayesha is a tragic character, for whom long life and great power are not sufficient.

She throws it all away in a fatal miscalculation.

This is still one of my favorite novels of all time.

However, like King Solomon's Mines, I think that a lot more could have been done with this. Maybe that is what makes them such great novels, they leave you feeling that you want more.
