Chosen by a prince... Who happens to be a vampire

Hi, my names Lucy and I was chosen by a vampire prince who is respected by everyone. He's one of 4 brothers. They're all attractive in their different ways.
There's two twins that are always up to mischief, one dark prince who hardly ever talks and when he does it's sarcastic and finally... One sweet and kind prince who listens to me when I need someone to talk to or helps me whenever I need it. This is my story.
