I know this is a bit of a long shot, but I was re-reading a few childhood books and came across The Time Travelers Quartet by Caroline B. Cooney and re-read all four books in a day. Does any one else remember these and would anyone be up for a more adult storyline involving Walker Walkley or Hugh-David? I'd love to find someone to play either man.
If not, I have tons more ideas at the journal, please take a look.
