The much-anticipated new novel by the New York Times and Sunday Times bestselling author of the Passage Trilogy - a mind-bending masterpiece for our world today...

'Next to impossible to put down . . . exciting, mysterious, and totally satisfying.' STEPHEN KING

The islands of Prospera lie in a vast ocean: in splendid isolation from the rest of humanity, or whatever remains of it. . .

Citizens of the main island enjoy privileged lives, attended to by the support staff who live on a cramped neighbouring island, where whispers begin to grow into cries for revolution.

Meanwhile, life for Prosperans is perfection - and when it's not, their bodies are sent to the mysterious third island: a facility named The Nursery, to be rebooted and restart life afresh.

Proctor Bennett is a Ferryman, who shepherds the soon-to-be retired into the unknown. He never questioned his work until the day he is delivered a cryptic message:

"The world is not the world..."

These simple words unravel something that he has secretly suspected. They seep into strange dreams - of the stars and the sea - and the unshakeable feeling that someone is trying to tell him something important.

Something greater than anyone could possibly imagine, which could change the fate of humanity itself...
