Kirkus Reviews called it a "must-read", noting Buchanan's "masterful job" of weaving historical figures into the plot and her "moving yet unsentimental portrait" of familial love, and The Washington Post'''s reviewer Susan Vreeland called it a "captivating story of fate, tarnished ambition and the ultimate triumph of sister-love."
