This is book one of The Echelon series and the main character if a young woman called Myla, who lives with Ona and her parents, who took her in and kept her secret all these years. You see, Myla is an aberration, a child born of two Decemites, something thought to be impossible, as normally any child born to a Decemite died at birth. They live in the Dirt, underground, doing all the menial and repetitive jobs that those who live in the Sky high above them would never consider doing. There is a massive discrepancy in the lives of these two factions of society, with the wealthy elites living in the Sky having fun and getting themselves drunk, and those in the Dirt having a miserable life and short ones at that due to the damp conditions and rampant illness. Each child in the Dirt is tested at the age of ten, to see if they are suitable to become Decemites, injected with nanobots to make them stronger and able to heal quickly, to then work on the Outside of the Dome everyone else lives under. They are trained for five years and at the tender age of fifteen are thought ready to collect resources from the Outside.
The Outside is a world of danger and land ravaged by radiation and toxins. There are also violent mutants and other dangers out there. The enhancements these called Decemites gain from their nanobots, allows them to survive long enough to collect resources to ensure the Dome and all the people in it can continue to survive. Ona was chosen as a Decemite and has her first mission coming up. Myla has to work a mindless job down on an assembly line, checking containers and putting stickers on dependant on whether they are safe enough to use or need more cleaning. She wanted to also be recruited as a Decemite, but failed the tests. Few Decemites live long enough to Ascend to the Sky levels, as the job is so dangerous. Myla has to hide the fact she was born with nanobots, as if she is ever uncovered, her sister Ona and her second parents would all be exiled and die in the Outside. The normal punishment for all who do anything wrong in their society or are got rid of or disappear.
When Ona goes out for her first mission, Myla waits for containers from her team to reach her conveyor belt and then runs up to greet her on her return, not something she should be doing and an area she is not authorised to be in! But Ona doesn’t return with her team and none of them will tell her what happened, keeping whatever happened a secret between the members of the team. A rule that is ingrained on them all during their training, what happens in the Outside is never talked about to others! Ona’s parents are heartbroken and her mother takes it really badly. Myla wants to do something, but her father tells her to speak to her grandmother, who does tarot readings and is her only true relative. The cards reveal that Myla has some big choices to make! She knows she can survive outside without an air tank and mask, but has never been on the surface, nor even seen the sun. She sets off to find Ona, camouflaged as one of the drone type workers who work on the outside of the Dome. She follows the buggy tracks to one of the vents, where the teams collect resources, but all she finds is a dead body of a young man, dressed very differently than anyone she knows. She then sees her first mutant, but it is someone she used to know who had disappeared, so this is where he got put!
As this boy, Jacob, attacks her, one of the Decemites called Lock, who is close to reaching his end of service time and then ascending, races up behind her and ends up having to rescue her from a large number of other mutants attracted by the noise. He has a buggy and was out alone, something he shouldn’t have been, but he was also looking for Ona. They end up being followed by a group of what Lock calls rebels, people who have lived in the Outside all of their lives! Something that the Dirt dwellers were told was impossible. Lock also knows a lot about what goes on in the Outside, and Decemites regularly trade with these people for food and other supplies. What other lies the leader of the Dome had been telling her people, is open for questions, that someone like Myla would never be given. They are taken prisoner by a young man called Ben and his group of people who were out on patrol. They are taken back to a larger group of people just like Ben, who have always lived in the Outside and survives by trading between all the different groups and mining for a metal called rigur, which they traded for gretha which helped them to breathe in the Outside!
She finds out her sister has been taken by another group and gets Ben to take her there, but finds none of them treat any Decemites well, nor they any Outsiders they come across. Even the Decemites are lied to, with some teams sent to eliminate Outsiders who fail to meet the rigur quotas, for whatever reason, and those quotas are always being raised to almost impossible levels. Ben lost his father when his mine couldn’t produce enough rigur and the Decemites left them without the agreed gretha, leaving them all to suffocate and die! The Dome’s elderly leader has new plans for mining rigur, which would bypass the Outsiders, leaving them all to die a painful death. Among all these groups of Outsiders, are families with children, who would be condemned by the actions of one person and her Decemites! Myla begins to come to realise that the life Ben and the others live, is nothing like what she has been brought up to believe in. Her only problem is that she begins to realise how brainwashed and regimentally trained Ona has become, trained to only believe in loyalty to her team and their leader, with very defined ideas about all those in the Outside and not believing anything any of them say to her, too ingrained in her training, to be able to think for herself, even when she sees the evidence of killings of innocents for herself.
Myla sacrificed her future, to save the person she has always regarded as her little sister, but has come to realise she can’t persuade her of the truth of what the Doe leader is having them do. Ona only wants to get back to her parents, by whatever means necessary. But now the secret is out about Myla and her nanobots, she will be in danger if she tries to return to the Dome. She has grown close to Ben and the others in the camp and enjoys the freedom of the Outside. She would love to stay with them, but the leaders plan will only increase and bring about all of their deaths, if she is allowed to carry on as she is. Myla believes her only choice is to return to the Dome and help from there. She will have to hope that none of the surviving Decemites recognize her, and that Lock, who now knows her secret, will keep her safe on her return. I can’t wait to see what happens in the next instalment of this series, as the fight for survival will continue and the truth about the nanobots put into the Decemites will come out.
