Bloomsbury presents The Kingdoms by Natasha Pulley, read by Theo Solomon.

Come home, if you remember.

The postcard has been held at the sorting office for 91 years, waiting to be delivered to Joe Tournier. On the front is a lighthouse - Eilean Mor, in the Outer Hebrides.

Joe has never left England, never even left London. He is a British slave, one of thousands throughout the French Empire. He has a job, a wife, a baby daughter.

But he also has flashes of a life he cannot remember and of a world that never existed - a world where English is spoken in England and not French.

And now he has a postcard of a lighthouse built just six months ago, that was first written nearly 100 years ago, by a stranger who seems to know him very well.

Joe’s journey to unravel the truth will take him from French-occupied London to a remote Scottish island and back through time itself as he battles for his life - and for a very different future.
