December 2023. The human race has fought a deadly virus and lost. The only things left from the world before are burning cities and rotting corpses.

But in London, one woman is still alive. Although she may be completely unprepared for her new existence, as someone who has spent her life trying to fit in, being alone is surprisingly liberating. Determined to discover if she really is the last survivor on earth, she sets off on an extraordinary adventure, with only an abandoned golden retriever named Lucky for company.

Maybe she'll find a better life or maybe she'll die along the way. But whatever happens, the end of everything will be her new beginning.
