The fourth in Marr’s Wicked Lovely series focuses loosely on Devlin, the High Queen of Faerie’s advisor-assassin, and Ani, the half-mortal daughter of Gabriel, leader of the Wild Hunt. Characters from other books play roles of varying importance as Devlin and Ani meet, fall in lust/love, and foil another attempt to create unrest in both worlds. This is a convoluted story, and despite frequent interruptions detailing character backstories and the inner workings of Faerie courts, it is utterly dependent on the rest of the series. Though the story ends with balance restored to Faerie, an ominous sense of precariousness leaves room for more.
