Shade's Children is a young adult science fiction novel by Garth Nix. It was first published in Australia in 1997 by HarperCollins.
Background
Shade's Children takes place in a not-so-distant future where evil Overlords have ruled for fifteen years due to a catastrophic "Change" which caused all people over the age of fourteen to simply disappear. Since then, the children have been rounded up and placed in prison-like dorms. No child may live past their fourteenth birthday (known as a "Sad Birthday"), when they are taken to the Meat Factory and their muscles, brain, and other organs are harvested to create creatures. These creatures are servants of the Overlords, and as such both fight in the Overlords' ceremonial territorial battles and hunt for the rare escapees who have managed to remove the tracer implanted in their wrist. There is only one exception to this rule: some young women are kept for "breeding" to maintain the supply of children, until a suggested maximum age of eighteen.
Escape is rare, based both on courage and ability. These teens are gifted, however, with "Change Talents" (side effects of the Change that are unique to each individual and generally fall into the category of psychic powers.) These talents are also dependent on Change Radiation, a mysterious field distributed by Change Projectors. This radiation allows the Overlords to control the weather and warp certain physical laws, which is critical for some creatures such as the Wingers, which would otherwise be too heavy to fly. The strength of the field is greatly weakened by water.
Several teams of escapees recruited by Shade live in a beached submarine, near a sewer pipe that allows access to an extensive sewer system. Shade is the only "adult" to have survived the Change. This, however, is mitigated by the fact that he is merely the uploaded consciousness of a real human scientist - a Dr. Robert Ingman. Shade knows that he is an uploaded consciousness and thus continually questions his humanity.
Plot summary
A boy nicknamed Gold-Eye, a fifteen-year-old, was born near the time of the Change. He was physically affected by the Change radiation and his eyes, including his pupils, are a bright golden color. He has a very special talent known as being able to see in the "soon to be now." He is also unusual in that he managed to escape and elude the Trackers and Myrmidons for a time. Yet as the story begins, he is finally trapped by the Myrmidons, and prepares to kill himself to prevent his organs from being harvested. This turns out to be unnecessary as he is saved by a team of strangers who stun the Myrmidons with a flashbang grenade and lift him to safety. These strangers are a team of Shade's Children, and after the group eludes some Ferrets by hiding in a tall building, he accompanies them back to the Submarine, Shade's Children's hideout.
Gold-Eye joins Shade's Children, and is soon sent off on his first mission with the team that saved him: Ella, Ninde, and Drum. Each team member is unique, and has Change abilities that correspond somewhat to their personality.
This mission is a critical one: to retrieve the equipment and data from Shade's abandoned laboratory on the University campus in the Department of Abstract Computing, including a device that measures Change radiation. It is also one of the most dangerous missions: All of the teams who have previously attempted this retrieval have been killed or captured in the process. Ella's team is successful, even when the Overlord Black Banner surrounds and invades the building, alerted by Leamington, a pre-Change artificial intelligence who calls the police on detection of the intruders. Leamington is notably different from Shade in that he is an artificial intelligence as opposed to an uploaded consciousness.
