So, the twist goes like this - the whole world thinks Guy A is the answer to the world's problems (a particular war) and basically 3 groups of people are after Guy A. 2 groups wanna use him and 1 group wants to kill him. But Guy A has never done anything special throughout the entire course of the novel, until right at the end, when it is revealed that Guy A wasn't the one who was prophesied to be "special". Because Guy A was adopted - the adoptive parents had swapped their real son for someone else's in an attempt to protect their real son from the future he will have (eg. people coming after him either to use him or kill him). Hence why Guy A kept trying and failing to use his "powers" he was told he has, but actually doesn't have. And then the real hero, Guy B, who's been in the story all along and travelled with Guy A etc, is revealed to have been the real guy everyone wanted. I know it depends on how you write it. But there're some things that are simply BAD ideas no matter how hard you try to write it. And I can't figure out if this is one of those occasions. I'm running into trouble on how to balance the focus, how to incorporate this twist into a war setting when the parents never really appear anywhere except for the beginning and a number of other little pitfalls of this idea... and wondering if it's worth it. So?
