I would look for something that really encourages storytelling skills as this is the key to the most advanced filmmaking - yet is so rarely focused on. Not talking about just writing but basic story telling skills. I don't know a book offhand... but if there is a fun one for that - it would be valuable if she's able to make the connection.

I think half of what I know about shot design i learned by reading the book at age 8: How To Draw the Marvel Way - there are a couple chapters in there about shot design which made a lot of sense... but, again, it might be confusing if you're thinking "this is a drawing book" - Ithink somewhere soeone actually scanned the four pages and put them online, I remember from a google search - it's only like 4 pages of the whole book.

I'm not much help, but I tried.

Check out "Developing Digital Short Films" or www.MyFlik.com for a free online digital storytelling class. As mentioned, visual storytelling skills are really important for young filmmakers to develop. This book and video "Writing A Great Script Fast" will jumpstart a young artist into a very high level of ability fast! Think of doing fun film projects together that you can help on :)
