Beware: This post has as many spoilers as Cersei has men thinking she's gorgeous...
Cersei Lannister from George R.R. Martin's A Game Of Thrones is a strong, beautiful, powerful woman who will do anything to—well, she'll do anything.
This Sunday, HBO premieres its Game Of Thrones miniseries, and Cersei's actions and motivations inspire much of the plot. Her diabolicalness is legend (for readers of the books, at least), and it's not until the fourth book in the series, A Feast For Crows, that we actually get events told from her point of view.
His lord father had come first, escorting the queen. She was as beautiful as men said. A jeweled tiara gleamed amidst her long golden hair, its emeralds a perfect match for her eyes. His father helped her up the steps to the dais and led her to her seat, but the queen never so much as looked at him. Even at fourteen, Jon could see through her smile.
[Clearly you don't want to get on her bad side...]
