Kingdoms are dying from a toxic by-product of magic known as "wraith," which has resulted in a treaty banning magic. But gifted 17-year-old Princess Wilhelmina struggles with weightier issues as she gathers information undercover in the Indigo Kingdom, whose royal family caused her parents' deaths. She intends to reclaim her birthright e throne in the conquered country of Aecor t the process is complicated by a masked vigilante who stirs her imagination and emotions, a vengeful companion focused on his own goals, and a compulsion to solve the riddle of the wraith. Hidden identities, allusions to environmental concerns, a clever heroine with a worthy potential love interest, and some monster-mashing fight scenes elevate this romance series opener. This has just enough action to potentially attract a wide audience and a cliff-hanger ending that will have many readers exclaiming aloud their impatience at having to wait for the sequel. Different aspects of the book may lead readers to Jodi Meadows' Incarnate trilogy or even The Scarlet Pimpernel.

Gr 7 Up-Wilhelminamore frequently known as Wilis a princess. However, she's a royal who's more used to stealing food than curtsying in a palace. Wil's homeland of Aecor was conquered 10 years earlier by the Indigo Kingdom and Wil and a band of other orphaned children of Aecor nobility have been living secretly as refugees in Skyvale, the capital of the Indigo Kingdom. The teen and the other refugees have plans to take back their home by infiltrating the palace. As Wilhelmina's mission inside the palace proceeds, it is complicated not just by her secret ability to practice magic—which has been forbidden for almost a century—but also by her connection to the vigilante Black Knife, a masked figure who helps the poor and the weak in the streets of Skyvale. Fans of Katniss and the Sisters of St. Mortain from Robin LaFevers's "His Fair Assassin" series (Houghton Harcourt) and other strong, vengeful female heroines will root for Wil, as she plots revolution, struggles with her conflicted feelings for Black Knife, and discovers more about wraith, the toxic by-product of magic. Although this series opener starts off with poorly executed exposition to provide the necessary background, the plot quickly picks up pace, and the highlights of this novel are the subtle lessons in the sacrifices and responsibilities of leadership, as well as the unique way in which magic use and wraith are echoes of our own world's debate about environmental justice.— Evelyn Khoo Schwartz, Georgetown Day School, Washington, DC
