Metamorphmagus Hair Colour Rules

What if Tonks wasn't meant to be with werewolves, but vampires instead? What if Tonks wasn't meant to be with a man, but a woman instead? Well this is the book where Tonks falls in love with a woman after her heart. Hope you all enjoy!!!

(PS: I got the cover from Google Images, so the cover and Harry Potter with all its characters aren't mine. All I own is Elizabeth and her contributions to the plot. Also don't plagiarize. Just don't.)
