Hello,

Being a Kindle reader I'm reading the books on e-book format, but now I want to order all 5 books on paperback for my wife. I checked Amazon but it seems there are 2 versions of covers for each book (covers with the faces and no faces). Is there a way to make sure I'll get the matching book for all 5? Were they published by different publishers? Or any other online / international retailer that sells only new sets?
