Before the pressure wave hit New Delaware, Sam and Cindy were drinking tea.Then New Delaware moved.Not far. Just 19.2 centimetres.Nobody knew why.Three hundred years after the events of Edge, humanity has spread beyond Earth. Ganymede has become a centre of industry and power. Artificial humans have advanced through generations of their own. And the future appears to have settled into something approaching stability.Then things begin to move.A Control Centre changes position without crossing the space between. An Edwardian photograph changes. People discover they may not be the people they thought they were. And a small domino becomes the doorway to something much larger.When Cindy is offered a choice between two futures - Red or Blue - she chooses neither.Soon the distinction between human and artificial, real and virtual, past and future begins to fail. A mathematician dead for centuries wakes up. Four ancient observers discover that time may be less important than agency. And somewhere, a dog has already worked out something everyone else has missed.Magenta is a science-fiction novel about identity, consciousness, choice and the inconvenient possibility that reality may not be obliged to obey the categories we invent for it.Because sometimes the problem isn't finding the right answer.Sometimes the question is wrong.
