Actually, that book is hardly new. I have a copy of it sitting on my bookshelf, and it was first printed in 1986. The cover on my copy has only minor differences from the picture, with the primary difference simply being that in the lower right hand corner on mine it says "ENDORSED BY AMIGA", with the old Amiga checkbox emblem. The subtitle on mine also says "Images" instead of "Image" and "Sounds" instead of "Sound".
As for the book itself, it's not that informative. It walks you through doing a few things with Deluxe Paint, Deluxe Music and Deluxe Video, but mostly it focuses on Amiga Basic without going into any great depth at all. If you actually see the book for sale anywhere, I can't say I'd recommend buying it as anything more than a historical curiousity.
