The Daughters of Freya is a mystery story told entirely through e-mail. I've thought of doing an interactive story spread across various web sites/blogs/e-mails, but the complexity of it seemed really overwhelming to me when I sat down to think it through.

Confining the story to just e-mail is certainly easier. I imagine you end up with a modern day version of one of the old epistolary novels like Dracula.

They'll send you the first 3 e-mails for free, but you have to pay $7 something if you want the rest. It only takes 3 weeks for the story to unfold. I'm intrigued, but it seems overpriced to me. I guess it would depend on how many e-mails you actually get over the course of those 3 weeks. I suspect not enough.
