“Ten realms” concept by Michael Chatfield became an instant hit as the audience saw the struggle of the hero through different realms one by one. Each time the target is tougher than the previous one and survival is the key for Erik and his friends. After every realm, they gain more power and skill which would help them in their further battles. Sadly when they come to the next realm they feel that their assumptions were wrong as the powers they achieved previously were of no use in the next step.
Each time it is a new devil they confront and getting killed is always easier than surviving in this kind of situation. Erik and Rugrat have entered the battlefield realm and for survival, they have to fight once again against forces that will torture them to the core. All their strength and courage will be tested to their full potential. [The Fourth Realm Audiobook]
If they fail this time they will lose everything which they have gained in the past including their lives. Whether it was The Two Week Curse or The Third Realm the struggle just never ended. The fourth realm ends with better results but Erik is not given time to rest in a corner for some time. [The Fourth Realm Audiobook]
Todd Menesses i.e the narrator of the series in the end provides us a tone in which we get the message that a new mission will start quite sooner. Celebration time is prohibited in this series because ending one mission means the start of another. Battles are deadly and if a listener is looking for some fun elements then this book will not provide it anywhere.
