"For those already familiar with the characters and the painstakingly built world from the previous volume, this title is even more compelling. The introduction of new characters (such as misplaced spirit Guin and traitorous Simeon) adds further depth, intrigue, and even humor to this romantic fantasy. Throw in shades of richly imagined Japanese-inspired culture and Armstrong's talent shines." ―
School Library Journal "[A] romance- and politics-filled sequel to Sea of Shadows. . . . Animal companions Tova and Daigo and unruly spirits provide comic relief. . . . [Empire of Night] develops . . . with brio."
