help! Big Difference between hardcover & softcover printing

I ordered copies of the same book in hardcover and softcover.
The softcover looks fine but the hardcover has printed much darker.

The jacket on the hardcover has a green cast to it and has obliterated most of the highlights, it’s a black and white image. It printed so dark you can barley make out the image.

I understand the dust jackets may be printed on a different machine, but why the discrepancy between the inside pages? Even the color cast’s are different between the two.

How would you correct for this in the future? Do you need to have separate files for both hard and soft covers to make sure they print properly?

thanks for any help.

the book in question is here,

After my post below I decided to analyze the images in my book.  One image in particular ’ APPLE MARKET’ stands out as good black and white printing with just some very minor magenta casting at certain angles and in certain light.  I seem to have given this image a bit more contrast than the others during the editing stage.  Maybe paying more attention to achieving optimum contrast is part of the answer.  Even so, if B/W images are important from a ‘Fine Art’ point of view, I would be reluctant to use blurb for the printing, as good as they otherwise are.
