This update reminded me of just how much I like this story. You've got such an intriguing premise, but you don't coast on the suspense and mystery. It's the characters, and how layered they are both individually and in terms of their relationships, that make this so compelling--well, that and your assured writing style.

I particularly loved this moment: “Ryan?” Kirsten called out as they drew closer. Sandy watched Ryan quickly flick his cigarette over the side; as if she couldn’t see it. He couldn’t help but give a small smile at that. Kirsten missed nothing. Seth waved at them, and Sandy smiled wider as he took a good look at his son – soaking wet and utterly relieved to see his parents. It wasn’t something Seth revealed often, but made his heart swell each time he saw it. It's a little microcosm of the Cohens+1 (at least as we fondly remember them from season 1): Ryan combining both defensiveness and respect by throwing away the cigarette; Kirsten, wary and watchful and protective all at once: Seth, realizing the gift that he has in his family; Sandy, mentally embracing them all, wanting to keep them all safe and together.

I'm very glad that you're going on with this. It's well worth the wait.
