Query: Does not compare to my other endgame book

I am 10 years old. I thought this book would add more after reading my other endgame book, CHESS ENDINGS: ESSENTIAL KNOWLEDGE (which is excellent). However, my first endgame book covered all of the important things in Maceunltys book plus a lot more. It was a loss of money to have bought this book.
