Manhart can be the one against whom the powers can be tested then Jack could use his full potential later on. Edward Castle is the sole creator of Challenge and Obliteration too so don’t take this book as a routine thing. The world that this marvelous author designs is always stupendous.
Jeff Hays has done the narration with extreme care and there is a clear hint that the author gave ample time to the book before starting the narration because he knew exactly where to put the pressure on the paddle. At every tough situation, the narrator has used a crunchy voice which only he could have provided. Just wait till the end and you will get surprised.
