Zigby and the Ant Invaders

We love the Zigby books. Already had three of them, so ordered this one also. Didn't realize until I was able to read it to my grandchildren, that the last page was missing. I usually sanitize the books before giving to the children and removed the sticker tags at the same time, so I didn't feel like I could return it. The Zigby stories are great, but the last page is not one you want to be without. So, for us, I guess it is a choose your own ending. From now on, I need to actually read through the books before cleaning them. Beware.
