Blood Knight-Book one

This story is unlike any other romantic vampire love story. It takes place when the main character dies from cancer in a hospital where she had five months to live. Before passing on, she meets an angel that gives her a second chance at life. She now reincarnates into the villainess, Princess Silvia Grace Crimson of the book she once read while in the hospital. Now that she gets a second chance at life, she must survive and change her fate. With any villainess writing in a story, they die in the end. She not only has to face each character but also the main character, Princess Roslie Bella Monroe, which it's her step-sister. She makes plans to try to survive her dooming death by making the male lead known as the blood knight, her maids, her lady-in-waiting, and the second male lead. She doesn't plan to fall in love. But as fate would have it, the male lead and the second male lead end up falling for her instead of the main character. What do you think will happen? How do you think Silvia's plans work out? Will Silvia fall to her doom?
