Oxford, 2050. Britain is fractured. The Divide – a vast wall – splits the country from Kent to Cumbria. Families and lovers are torn apart. Civil war and economic collapse have left mistrust, propaganda and fear in their wake. Petrichor Jones, a specialist in Roman bronzes at the Ashmolean Museum, longs to see her sister Jasmine, who defected years earlier to Anglia. But Oxford, now capital of Wessex, is suffocating. Rumours swirl of the Dark Politic, a clandestine force controlling the media, and Petrichor begins to suspect her own boyfriend may be working against her. When she encounters the secretive Astronomy Club, she is drawn into a perilous underground network. With their help, she attempts the dangerous journey beneath the Divide. Along the way, she must decide who to trust, confront betrayal and risk everything to reunite with Jasmine. Love, resilience and rebellion collide in a world where freedom is fragile and lost innocence can never be regained.
