Life After Death?
MC recently lost YC in a tragic accident, they were a perfect couple. But she just disappeared, without a trace. One day, he find a note for him. A letter from to her meet. This cant be real, dead people dont leave notes.....right?
-I was thinking YC could be either a vampire, ghost, or MAYBE a zombie(maybe we can work with this)

Blood Red Roses
MC got ina tragic accident, and was saved by YC, a powerful vampire countess. Daughter of the Count of the most powerful Coven, the ones who all other covens have to follow. He isnt a vampire persay, but a human thrall. Thralls live MUCH longer then any humans. To them, 100 years is like 1. Her reign as empress will soon begin. Others arent too keen on it, and some dont like how close YC is to MC. But is there a deeper reason as to why she turned him?
