I received this book from NetGalley in exchange of an honest review.
It's 500 years in the future and the humanity is gone. The Earth's inhabitants and guardians are genetically engineered beings, called the Erta, created with the purpose of stabilize and heal the planet. Now that their purpose is achieved they have to decide what to do: resurrect the Homo sapiens like they promised they would and risk the planet's health again or let the humanity vanish for good. They decide to raise one child, an experiment, to see if humanity is worth saving.
Ima, an Erta that was responsible for the atmosphere's health, is chosen as his "mother". But the logical and rational Erta finds herself with a challenge she didn't thought would be so bigger, bringing her to question her life and beliefs.
The Human son is a sci-fi story, told in first person by Ima, who spent all her existence believing in equations, rules, agreement, purpose and that sees her whole life disrupted by her "son' " existence.
Unbelievably funny are her memories about Reed's first days of life and years, her inability to know why he cried so much, why an infant would wake up so many times at night, how to feed him, why he needed so much time and space. From being an important member of her community in Fane, a scientist, the atmosphere's hero, alone on her balloon, Reed's presence pushes her away from other Erta, who can't understand (or won't) her "project" and start to see her as an unusual Erta, alienating her.
Told by her POV, the reader follows Ima and Reed as they grow, as they discover they love and care for each other, as Reed starts to talk, to walk, to discover the world around him, as Jorne begins to be an important part of both Reed's and Ima's life, as Ima starts to question the truths she always believed in.
As Ima discovers the Sundra's way of life, Jorne and follows Reed's curiosity about the world, becoming more and more "human", detatching herself from her old beliefs and truths, so the Erta start to become different from what they were and disagreement and violence spread, while they try to escape the Earth, using the trascendence.
The human son is a wonderful sci-fi book, a tale of love, growth, truth and humanity. Seen from an "alien" (so to speak, since Ima isn't human) it shows the damage inflicted on Earth by humans and their greed and indifference, so it's a book with strong themes and messages about what it means to be human, to love, to care, to protect.
I found this book beautiful and captivating. I was fascinated by Ima and the Erta and I liked her relationship with Reed, reading its development, from being her "project" to her son.
The relationship between Ima and Reed is one of the most strong and important in The Human son, but the one with Jorne is important too, because through his help and presence, Ima starts to see Reed as son, to ask herself question, to try to discover the truth.
I devoured this book, because it was fluid, but in some parts there was too much scientific prose and processes explained, so it slowed the book, almost stalling my reading.
But it's a negligible detail, because the story is moving, funny. The Human son is almost a love letter from a mother to a son, talking about what it means to be human, to love, to see another being grow and change.
