I would like to begin by saying how much I appreciate the amount of research and effort that went into recreating England and Arabia, before, during, and after WWI. Donnelly did her best to capture the anguish and despair of a war torn era, too intense to even begin to imagine. 
 As with the first two books in the series, the plot is too intricate to even attempt to predict; entwining stories together into an impossible braid. Yet, somehow, by the end, there isn't one loose hair. I am able to put the book down feeling entirely satisfied. 
 Donnelly is master of putting Murphy's Law into writing: If anything can go wrong, it will. Her characters went through absolute Hell, time and again. I was in constant agony while reading this entire series, but only for the character's sakes. I absolutely recommend this series.
