Prologue Josh idolizes his older brother, Max. They look alike, they sound alike andbthey even have the same interests, including their favorite online role-playing game, Genesis Alpha. But josh and Max have a much deeper connection - because Josh was born for a reason. When Max was very ill with cancer, it was Josh's stem cells, harvested before he was born, that saved Max's life. Then, suddenly everything changes. Right in the middle of a game of Genesis Alpha, Max is arrested for the brutal murder of a young girl. As his family are flung into turmoil, Josh desperately tries to reconcile the brother he knows and loves with the monster they are talking about on television. At the same time he also struggles with an unnerving sense of guilt: if his stem cells had not saved Max's life, would this girl still be alive? But this is only the begining and, before the end, Josh uncovers startling revelations - revelations that could have devastating implications not only for Max's future, but for Josh's as well. A fast-paced, chilling debut novel exploring the origins of good and evil and the thin line between science and morality.
