In the World I Wrote

Ethan Winters loved writing. It was his way of desconnecting from the real world and he loved creating new things. But... what happens when one day he finds himself in a story he wrote? He knows who's supposed to die, who's supposed to live. A world with mana and powers. Will he be able to survive his own world? Can he return to his original world? Will the story change now that he's in it?
