His Illegal Self: Peter Carey

Seven-year-old Che was abandoned by his radical Havard-student parents during the upheaval of the 1960s, and since then has been raised in isolated privilege by his New York grandmother. He yearns to see or hear news of his famous outlaw parents, but his grandmother refuses to tell him anything.
When a woman named Dial comes to collect Che, it seems his wish has come true: his mother has come back for him. But soon, they too are on the run, and Che is thrown into a world where nothing is what it seems.
