In the Time of the Butterflies by Julia Alvarez

Britt's take

Four sisters. One dictatorship. A story about what courage looks like when the cost is everything. Inspired by the true story of the Mirabal sisters, this novel transforms their loss into a lasting symbol of national heroism, bravery, and martyrdom. I read this over a decade ago and it has never left me. If you want historical fiction that feels genuinely important, this is it.
