It's the end of the twenty-first century. Technocrats rule, and robots take care of humans' every need. Your house watches you, knows your secrets, and talks to you. And your closest friend can be—a machine?
Gavin Bell and his teenage sister, Fleur, live in a middle-class family. Their much-loved, old-fashioned robot Grumps is running down and can't be repaired, so a scientist friend loans them a brand-new, experimental robot to help Grumps out. EGR3, known as Eager, learns from his experiences, as a child would. Eager feels emotions: wonder, excitement, and loss. When the ultra-high-tech, eerily human BDC4 robots begin to behave suspiciously, Eager and the Bells are drawn into a great adventure—one that is sometimes funny and often frightening. As Eager's extraordinary abilities are tested to the limit, he tries to find the answer to this question: What does it mean to be alive?
