The audio narration of the complete series here is done by Steve Campbell. The performance is so beautifully done that you will feel like having a movie going on in your head.
The world was not exactly how they left it. When the bunker airlocks released all of them after a couple of decades in hibernation then the survivors came across a barren, silent world outside. But, they were not at all alone. There was a presence here for sure which was all alive in the dust. That was the spirits of the planet earth which were malicious and benevolent just as they interacted with the human remnant. Milton was haunted by a violent past that he was not able to escape from. That was the case despite having the superhuman speed which was bestowed by the spirits.
Daiyna was not interested in bearing the next generation. She was equipped with the night vision and was resolute to abolish all of those flesh-eating mutants that were lurking in the dark. The author did a brilliant job in terrifically ending this trilogy. The narration was the best part of the series and through that, you will be able to feel the true emotion of the characters.
