Ice Like Fire question

I live in the Netherlands which means some books are sold in US version (which means, thin paper and a shiny cover) and others have a UK version, which has thicker paper and different kind of cover. Also, the size of these is different (I'm talking about the paperback by the way). Also, on the back the price is either in dollars or pounds.

I didn't even know about this until recently, but now I have a problem.

I bought Snow Like Ashes and when I wanted to get Ice Like Fire, I noticed the difference, even though it was in the same store. Later someone told me UK and US books are different, so I went to search for the UK version. Problem is, I can't find it anywhere. I hate to see that difference in the series on my bookshelf!

I asked an online store whether their version was US or UK and they told me there was no UK version. Can anyone confirm this? Because of there's not, I'll get it in hardcover and replace Snow Like Ashes as well.
