Tryin To Write A Book (Again)

Ok I'm going to attempt to write a book, I've tried to write a few already but I keep hating it and well I'm kinda looking for some help at times I'm a perfectionist and what I write just sux to me and I start over so ya lol anyway ill tell you basic story line and if you can give me some help also idk when ill be able to get on here again so at the end is my school email anyway thanx for takin time to help if you do, if I don't respond to you in 2-3 days email me

Ok the story goes somewhat like this:

There are two brothers (One is roughly based off of my RP character and the other idk) but both get cassed out of the kingdom even though they were princes and ya. In ones exile he gets transformed into a vampire(becoming a lot like my RP character but a lot more demented) and the other becomes a old classic Robin Hood type character. Anyway the king soon dies and what not and message soon spreads that the princes need to be welcomed back because there is no other heir to the throne and everyone else in the kings family is dead for a reason I haven't thought of. So ya both the princes go back to the kingdom but according to the kings will they have to prove themselves first and do some quests and what not. So ya that's as far as I got so far and well I want everyone to love the Robin Hood character and hate or somewhat dislike the other but near the end I want to have the Robin Hood guy die because of some horrible thing that he did and have the vampire actually be the good guy, despite what has happened

That's all I can think of right now so ya, and I need help with sub-plots, events, the Robin Hood guy, the quests, the evil things the vampire does and stuff like that maybe even a few other plot twists in there lol anyway that's what I need help with and if its a long idea please email it to me thank you all for your help
