I'm going to miss Sasquan (darnit!), but in regard to your YA SF panel -- in case you hadn't known it, there is in fact a YA-specific tie-in novel spun off from this summer's Tomorrowland movie...and it is dead flat fascinating. Essentially, it's a pulp adventure that is part Tom Swift, part pure dime novel, part Saturday afternoon serial, and part love letter to old-school SF geeks. (Believe it or not, none other than Forrest Ackerman has a cameo....) I found it at once utterly wonderful and deeply odd, and I think it's definitely worth seeking out.

Two links, then: Disney's Web page for the book, and an EW profile of book and author(s).
