Okay, so, I had a cool idea for a book it'll be my first story that I wrote for fun, I wanna know if it's a good idea, or if it's already been taken, or stuff like that, here it is:
Christopher is a knight for a kingdom (dont have a name yet) at war with dragons, in medieval times. He goes out to a dragon's cave in an attempt to kill it, and when he gets to the dragon it doesnt attack him, so he charges at it, and it lifts it's claw and touches him in the forehead, and mutters something in an ancient language. Chris instantly falls asleep.
Christopher wakes up in Egyptian times, and freaks out, wondering if it's a dream, he runs outside, but no one's there. so he stays awake for a few days, wandering through the desert looking for people, but no one's there. After a long time in the desert he collapses and falls asleep, and wakes up in another time era, in another city with no one there.
Basically, he was cursed so that everytime he falls asleep he goes to another age in time, and he's inside of his own world, with no one there.
Anyways, for the end of the book a year or so will pass and he'll wake up back at his kingdom, with no one there, and he'll venture to the cave, see the dragon about to touch it's claw to his head (he's at the point in time now where he got cursed), and kill the dragon, instantly fall asleep and wake up in his home, with his family around him, and be informed that he was found sleeping near the dragon, and the dragon was dead. then he'll be called a hero by his people, the end :D
so, what do you think? should I pursue the idea?
