I read part of a book about a girl who is stuck looking as a 22 year old even though she is centuries old. Her mum was a vampire queen and her dad was a lycan alpha but they were killed. She is a vampire-lycan hybrid and the last one of her kind. I think her name was Camilla. Also remember that the male lead was Lucas I think and each main character had their own chapter.
I read a bit of it yesterday on Facebook but can't find the post again today.
