Query: Do not buy

Do not buy books from this publisher. As the other review says, there are bizarre typos and in at least one case every other page of the book I received from them was missing. I wrote to the registered principal for the company but received no response. It's one thing to have a few typos here and there but when so many pages are missing that it is useless to have a reprint, that has crossed the line.
