Originally wasn't sure about this one because of the compulsion Charlotte was under. I needn't have worried. I thought Charlotte a strong, capable character and a good match for Kieran. I like that while each book is about different couples getting their HEAs, there is also an underlying story line that ties all the books together (in this case ultimately freeing the fae trapped in Piefferburg). And boy, with that story line, things are heating up. There is a bit of a cliff hanger ending, book 4 had better wrap everything up.
