How do these storylines sound ?

Ok , so i know that vampire books are waaay over done . But , what if the storyline was completely original , and not similar to any vampire books ? Like , a human who is turned into a slave , and then sold to her ex - best friend who is now a vampire ? ( the vampire would be a boy )

Next , what about an arranged marriage ? I have never seen a book like that before . Maybe because it’s not a good topic , or because no one chose to write about it , what do you think ?

Finally , what about a war between vampire hunters , and vampires , that is resolved by the vampire prince , and the head vampire slayers daughter ?

I have a good sense of how i want these storys to be , but im not going to get into detail with them on here because you never know if someone else might take your idea , but i was just wondering if anyone would even be interested in reading these ( I want to be a writer when im older , and plan to start practicing now )

Also , i was thinking of maybe combining these 3 different plots into 1 big story ! Any opinions ?

I know , 2 of these topics are kinda like the typical vampire story , but writing about the supernatural is what im best at , and at the moment those are my only ideas . So , what do you think of them ?
