I agree to this one hundred percent. Actually, L.J. Smith wrote more on Ash and M-L on her website. It can be found http://www.ljanesmith.net/stories.php I haven't read it yet because i really want her to make it into a book. Maybe it will be in Strange Fate. Ash and Mary-Lynnette > Edward and Bella!
I just looked at the link you gave me. I didn't read it yet but I wanted to let you know that at the end it says to be continued so I bet it's going to be a book at some point. I sure do hope so. I kinda feel the same way about not reading it because I want to wait for the book. I feel more strongly however about Midnight sun haven't read it and won't until SM has it published!!!
