Well, Mark is still reeling from the death of Rebecca; his life is falling apart. He ends up having to go back to New York on a family emergency and is back in contact with Crystal, whom he puts in charge of his San Francisco gallery.
If you remember "The Master Undone" he has brief thing with Crystal, after finding out that Rebecca is dead [although her body still has not been found] and things look like they might get rekindled between Crystal and Mark [which I really hate because I'm hoping that in book 5, which will focus entirely on Mark, that they find Rebecca actually alive].
I love/hate this series, its too much having to wait for the remaining books to be published.
Rating 3 out of 5
