There are lots of stories where someone finds out that everything they know is wrong, but The Sword shows how great they can be. Dara Brighton is a paraplegic college student at home with her family one night when three mysterious strangers with supernatural powers break in. They keep calling her father Demetrios and demanding that he turn a sword over to them.
When he refuses to acknowledge what they are saying or possessing any sword, they kill him and then turn to killing his family. They do not kill Dara but leave her without hope of escape in a burning house. As the house collapses she falls into a space underneath the foundation and finds a sword sticking in the ground. When she grasps it, she is instantly imbued with incredible power and can again walk. After she escapes this wreck, she begins to piece together what has happened, beginning with the possibility that her father was over 3000 years old.
