What do you think about my book idea?

My book tells about Harmony, an ordinary girl who one day finds out she's actually a powerful witch. She then has to attend a special magical school, where all witches, wizards and supernatural beings go to. In there she meets the school's bad boy, Eric, and falls in love with him. There's only one problem: Eric is a vampire, has been for hundreds of years! And as if that didn't present enough challenges to their relationship, there's an ancient right-wing conspiracy going on. Mysterious brotherhood, lead by the sinister dark wizard Wal-the-mart, is protecting a secret that would change the world. The secret is... that the president of USA, Barack Obama, is actually the last descent of Jesus Christ. Can Harmony and Eric together defeat the forces of evil and reveal the secret to the whole world, ending the tyranny of the right wings?
