When physicist Robert Strong – newly unemployed and single – is offered a hundred thousand pounds for a week's work, he's understandably sceptical. But Victor Amos, head of the mysterious Observation Research Board, has compelling proof that the next round of experiments at CERN's Large Hadron Collider poses a real threat to the whole world. And he needs Robert to sabotage it.

Robert's life is falling apart. His work at the Dark Matter Research Laboratory in Middlesbrough was taken away from him; his girlfriend, struggling to cope with the loss of her sister, has left. He returns home to Scotland, seeking sanctuary and rest, and instead starts to question his own sanity as the dead begin appearing to him, in dreams and in waking. Accepting Amos's offer, Robert flies to Geneva, but as he infiltrates CERN, everything he once understood about reality and science, about the boundary between life and death, changes forever.

Mixing science, philosophy and espionage, Libby McGugan's stunning debut is a thriller like no other.
