The Lancaster Rule. The Lancaster Trilogy, #1

When destiny calls, it can take 300 years... The world loathes Josie Bettencourt's kind-pod-survivors from the past. When she awakens three hundred years later, she discovers what falling into hell is like. Stalked by uncertainty and death, her new life pitches from one extreme to the next. She is soon arrested and taken straight to the Citadel, the heart of the Lancaster regime where they have ruled tyrannically for over half a century.
Now young John Lancaster is in power, hoping to make a change, to erase the wars, oppression and unimaginable terror. When Josie meets the frighteningly powerful John, she wonders if he really is the so-called tyrants' spawn? But like a plague from the past, her presence in the future draws dangerous forces together. Josie soon discovers who the true tyrants are by unraveling a terrifying plot to take over the world.
And she realises that her life in this new future are indelibly linked to the one she left behind.
