Succubus is book 4 in The Dream Series, written as a novella to fill in a few gaps - which you know by now is something I love to do. Rather than continuing the plot from book 3, it takes the reader back in time to just after Elizabeth "dies." You'll find it a bit more erotic than the first three books, so fair warning What happened in the 400 years between Elizabeth dying in her castle tomb and the birth of The Chosen One? Take an erotic step back in time and learn more about what Elizabeth and Sebastian were up to as they prepared for that monumental event to take place. They certainly didn't get bored while they were waiting, that's for sure
