I reincarnated as the vampire's maid

Imagine you just died in the real world and then just after you reborn you know you will die again. What will you do?

Sua reincarnated as an unknown identity maid in the novel that she read. In short form she has reincarnated in the book. The book she read is about a beautiful female protagonist that all people love her. It's not really good but she read the book because that book author is her sister. So her sister needed a support even the book is typical blond girl with ocean eyes. It's okay if she was reincarnated as a usual maid but...

She need to serve the duchy. The duke family is a vampire that thirsty for blood. That's why she know she will die sooner than expected but what if she can survive?
