I found this site:
Harper's Island - CBS.com that has full episodes to view! There is not an Episode 12 or 13 yet, but hopefuly they will add them now that they have aired. There was one other episode I missed during the season. I will have to figure which one and watch it too. Maybe these will help anyone else missing out on one of the shows.
I don't get into any of the reality stuff so this is one of the first series type TV shows that I have really gotten hooked on in a long time.
