The year is 1932, and Dr Isla Fenwick has little interest in marriage, until a reunion with an old friend unexpectedly blossoms into an engagement. But before committing to her new life, Isla is determined to fulfil a long-held promise to practice medicine in India. With her fiancÃ©’s blessing and a promise to return within the year, she sails to Calcutta to set up a midwifery clinic. There, she immediately clashes with the arrogant and aloof Professor Saxon Vickery. But as they work together to help their patients amid the complexities of 1930s India, a grudging respect evolves into something deeper. And when tragedy leads them both to the tea gardens of Darjeeling, Isla will be forced to decide once and for all where her heart and her loyalties lie.
