Hawkes Harbor revisits the early Barnabas/Maggie storyline. It's told from the perspective of Willie Loomis, who is called Jamie Sommers (the same name as The Bionic Woman
). He bonds with the kidnapped Maggie counterpart. They end up having sex. It's very Stockholm Syndrome.
Somebody gave me the book for Christmas one year. It was okay but I could certainly see why it was not published as a DS novel.
