Dar, Inkdeath has been out for ages and ages.
Just go to your local chain bookstore and go to the children's section. I'm not sure how yours is orgainzed but it's in there somewhere.
I really wanted to see Inkheart the movie but then the universe conspired against me. When I wanted to see it I got sick. And I stayed sick for a month and then some weeks after that, until it wasn't in theaters anymore.
Coincidence? I think not...
