I had a problem with a similar EM book.
When I xfered it, it became a regular editable book. You should check if you can edit the title and author and text, and if so, then it's pretty much worthless.
Anyway, people here are not so crazy about closed books with no particular color (like abyssal, tye, europa gold). So at best, I would say each book should be in the 6-12m range.
Hope this helps.
