I'm looking for a story that I didn't finish and whose name I have forgotten. It was about a boy who feels inferior to his twin brother. He gets hit by a car (I'm pretty sure) and dies, but as he is dying, he hears a voice that asks if he would like a second chance. The boy accepts and wakes up in a strange magical world. He wanders around and meets two men who, if I remember correctly, try to battle him for reasons the boy doesn't understand. The person who saved him from dying before rescues him again (I think), and then informs him that he is now the savior's servant/knight, or something along those lines. When I lost the link, the boy still didn't know the identity of his savior. The mysterious king of the magical land had been mentioned, and I was thinking that the boy's savior might be the king, but I don't know that for sure.

I didn't get but a few chapters into the story before I lost the link, so this is all I can remember, and even then, I could have misremembered a few details. I hope I there is enough here for someone to recognize! Thanks for your help!
