Imagine Queen Elizabeth I never ruled. England and Scotland never unified. It's 1845 and the two countries are again at war. Catastrophe has struck. Rather than returning to England in triumph, Clara finds herself injured and alone, imprisoned in Edinburgh castle, unsure whether her friends are even alive. But the Scots aren't what Clara imagined. Amputee doctor, Jamie, treats her broken bones instead of adding more. Edinburgh is also a surprise - half-destroyed by bombs that fell the same night London was attacked by airships. As trust grows between the two would-be enemies and secrets are revealed, they start to uncover the depths of Duke Murgatroyd's treachery. When a revelation about Clara's past occurs, peace is suddenly within reach. Is tinker Clara strong enough to make the sacrifice needed to save her country?
