Is this a book or leaflet? I contain 5 pages including 2 pages ad. The price is too much. It is my fault not see the book specification. Two writers jointly wrote this 5-page book. Congratulations!

The topic of this book was new and interesting for me. But I was disappointed with reference less, incomplete writing. Moreover, price is too much high. Really, too high price.
