Outline of Arthur's Heir
Chapter 1: Logan and his little sister Andrea are out in the woods in England, practising archery. They come across a circle of standing stones and when Andrea enters the circle, she disappears. Immediately, Logan follows after her and ends up in the Medieval Ages.
Chapter 2: Unaware of where they are, they find a boy named Arthur who provides them with Medieval clothes and a place to store their modern ones. Soon after, they find the Sword in the Stone.
Chapter 3: Logan pulls the Sword out and practices with it a couple of times. Arthur comes around the corner after storing their modern clothes and spots Logan with the Sword.
Chapter 4: Arthur tells the village, despite what the siblings protest. The village grabs Logan and makes him King. Andrea is locked out of the castle with Arthur and isn't allowed in.
Chapter 5: With the help of Arthur, Andrea disguises herself as a servant to sneak inside the castle and get Logan out. She sends Arthur to find the standing stones that sent them there.
Chapter 6: Andrea gets caught and thrown into the dungeons. No matter what Logan said, the people wouldn't let her go.
Chapter 7: Logan breaks Andrea out of the dungeons and they escape the castle the way Andrea came in.
Chapter 8: They put the Sword back in the stone and find a frantic Arthur. They ask him where the circle of stones is and he says that Kay's sword is missing. They direct him to the stone.
Chapter 9: Before leaving, they watch Arthur pull the Sword from the Stone and run back to Kay. They enter the circle and finally go home.
