Unfortunately, there's not much I can do at the moment to reduce memory usage by the app, at least not without taking apart the PDF merger and seeing what I can do there (and that's a slippery slope). I'll do my best to look into that and see what I can do, but otherwise, feel free to shoot me an email (my email address is public), and we can look into other options for getting you your book.
