I've been working on a book idea for about 4 years now. Its something that came into my head at the beginning of high school (7-8 years ago now), but I never really got into it until I told a bus with a majority of girls about it and they all clamored for me to keep writing it (not saying writing is a female thing, but that the girls at my high school seemed to want me to be a writer). After a while, I realized that the scope of this idea may be a bit big for my first attempt at writing, but its the only reason I actually starting taking an interest in wanting to write books. I wanted to throw the idea out to see whether people thought it was too immature or if it was something that could work (and if it could work, what would be some guidelines from keeping it being a waste of time or become too immature of an idea). I've written the first book already, and is very much in rough draft form; I'm planning to put up the first chapter in the review forum within the week (just gotta do some other reviews before then). The book is about a high school graduate and his friends are whisked off 10 years into the future where they learn Satan and his hordes of demons have taken control of the world. And (you guessed it) the protagonist is the only one that can save them all. The story takes people across the whole world, experiencing different sins and the change this new world has come to bear. However, the protagonist holds a secret that he doesn't even know about until later in the series (did I mention that its set to be a 12-book series?). These secrets start to change the mind and character of the protagonist and could even threaten the fate of this new world. Will he become the hero Earth needs in its time of need, or will he fail in his mission due to the darkness enclosing around him? So what do you think of the idea? I can't tell you too much since I haven't finalized anything past book 1, but I pretty much have the full story in my head. Its pretty much a science fiction read, with action and adventure in it. Too childish? Best-seller potential? A Good Start? Advice and critiques, please, and thanks in advance to all who read and/or post! BTW, the name of the first book right now is The Descending Fire, if that helps with it at all.
