Sam, a teenager who grew up in a cave in Ireland after the End War, is thrust into a world very unlike their own. Sam decides to help a mysterious stranger named Carter who controls a dragon, but not everything is as it seems as Sam learns the truth about what dragons really are. Sam is imprisoned in the new world, awaiting trial for shooting Carter, when Sam is violently attacked in a prison cell. In desperation Sam fights back, but will the jury's fear of outsiders doom Sam to a death sentence? And if Sam is freed, will Carter's army turn Sam into a cold-blooded killer, like the ones that murdered so many hunters from the Crag? Sam's world is turned upside down in this dark tale of finding one's identity and allegiance. Sky Machine is the sequel to the novel Sky Child, and the 2nd book in the Sky Child trilogy.
