A Kindle's New Home

My Kindle needed a place to rest so what better than it's own library..? 

I have been putting this little diorama together over the past week or so and it sits snuggly in the side table/cabinet next to my reading chair. 

Each of the books were made individually but to stop a mini disaster I have glued them in place. I have included a mini boat and the latest copy of the NT magazine. 

Can anyone guess what the 4 coloured books in the thumbnail may represent? The one on the right will be for the next in the series if there is one and my guess is it might be a mustard colour.
