Hey there, let me join, too?
I present you my idea for a bookcover, dear Aria-chan.
The idea behind:
The werewolf and the vampire have been good friends siince childhood and evereything was good until the werewolf fell in love with a witch. The witch pretended to love hin back, while in reality she was just using him to get rid of the ones she didn´t like or were likely to interfere with her schemes. Another reason she went along with the werewolf was because he is friends with one of the mightiest vampires alive. She told the werewolf that the vampire was trying to win her over which made the werewolf unhappy till the point where he couldn´t believe his old friend any longer and felt betrayed by him, not realizing that she was playing a trick on him.
The vampire who wasn´t blinded by love found out that she made her supposed boyfriend fight against various creatures making him believe the vampire sent all of them and wants her to set his best friend free. The witch tells the vampire he could have the useless werewolf back when he turns her into a vampire. The werewolf makes it to them when the vampire transforms her and feels even more betrayed, but after the successfull transformations she injures the vampire deeply to test her strength and tells the werewolf how she played him while she goes for killing him, so she could absorb his powers, too.
Yeah, however the end will be.
Plase enjoy. I hope you like it.
