So, as well as having book two released, book one has been given a fresh cover. The blue cover is my original, first book, and has nothing new in it – if you have the black and yellow cover book then you don't need to buy the blue cover.
The new book is a bit bigger and has the red cover, and of course a different name, but it's similar enough that people might make a mistake and pick up the wrong book.
Here they both are so you can compare them.
So – original book on the left, new book on the right. I just want people to know so that they don't get the wrong one by mistake.
