If you have not read the beginning, I suggest you get them here:

Summary:
Alexander's parents went back to Romania so Raven and Alexander have the whole creepy mansion to their selves except for the butler. Any hoo....in this particular book Sebastian comes to visit Alexander. Sebastian is Alexander's best friend and Raven had no clue that Alexander even had a best friend. At first, Raven doesn't like that he arrived, thinking it would cut into "couple time" but actually Raven grows to really like Sebastian (as a friend) and loves having him around - the only problem is that Sebastian falls for Becky (Raven's best friend) and Raven is not happy about that. She likes her best friend mortal. So here our book begins.
