1855, Lucknow. As tensions simmer in the heat of colonial India, a prince of Avadh and an English woman defy their societies' prejudices to fall in love. But in a world where private happiness is at the mercy of wider events, even as Salim and Rachael are drawn closer together, their privileged lives are about to be torn apart. Troule begins when the British annex Avadh and banish the king. Determined to recover what is rightfully his, Salim seizes the chance to fight back when a small mutiny flares into bloody rebellion against British rule. As unrest spreads across the subcontinent, the ancient city of Lucknow proves one of the most dangerous places to be. Torn between their loyalities to each other, their families and the oposing sides that threaten to raze the city to the ground, can Salim and Rachael's love prove strong enough to rise above the devastation surrounding them, and survive together to a world beyond?
