Indigo Doves offers a great new perspective on historical fiction. The trope of the contemporary twist (a historical narrative 'rediscovered' in some way by a character in a modern timeline) has often been done before, but rarely so successfully, nor have the two periods been so seamlessly integrated.
The characters themselves are beautifully multidimensional, and resist the possibility of being archetypes of their period, occupation, gender, or anything else. Instead, Masters has created a world in which individuality shines through, emphasising a real sense of believability and immersing the reader in a reimagining of the American Civil War.
The story is consistently brilliant, and at no point did I find it was predictable, which was also refreshing! A great book all round.
