The second half of Leena Likitalo’s Waning Moon Duology, The Sisters of the Crescent Empress, picks up directly from the close of the prior book (reviewed here). The five sisters have been sent to Angefort, confined to an isolated estate where exiled royals often find their ends in the Empire—and the house is as haunted as its new charges are. In the capitol the usurper, Gagargi Prataslav, feeds souls to his Great Thinking Machine to run the calculations of a truly equal division of empire while a civil war rages on.
Celestia is weakened from the loss of a portion of her soul; Elise’s combination of guilt and moral righteousness weigh her down; Sibilia is neither girl nor woman, trapped in age between the two pairs of her sisters; Merile is old enough to know that something is terribly wrong but not old enough to understand it; Alina’s grasp on her physical self instead of the world of ghosts and shadows is tenuous at best. The girls must attempt to work among themselves to design an escape and a return—if it’s even possible.
