Clockwork Princess

Clockwork Princess by Cassandra Clare, 2013 Walker Books

     Jem and Tessa are planning their wedding, Will is distraught at the idea of losing Tessa and the arrival of his younger sister Cecily, and Charlotte--along with the rest of the Institute--are reeling from the last battle with Mortmain, the Magister, when Gabriel Lightwood arrives with news of his father's demise. The inhabitants of the London Institute rush to help dispatch the Lightwood patriarch turned demon and protect the world from another monster.
     When the Lightwood brothers return to the Institute the Consul, intent on removing the independent Charlotte Branwell from her position, uses their father's state and Gabriel's guilt in being part of his demise to blackmail the boys. The young men use the opportunity to feed false information to the Consul attempting to thwart his plans.
     Mortmain maneuvers to monopolize the drug that keeps Jem alive in an effort to coerce the Shadowhunters into handing Tessa over, or have her surrender herself for her fiancee. Jem refuses to allow the sacrifice insisting he would rather die than give Mortmain the satisfaction of defeating the people who could protect the world from his plans.
     When an attack on the London Institute brings Tessa into the Mortmain's grasp and nearly kills Jem, the Consul refuses to acknowledge another attack is imminent. Rather than going after Mortmain and attacking he cautions waiting and preparing for the inevitable attack on London. His cautions are nearly the undoing of Shadowhunters when Mortmain's Infernal Devices attack the Council meeting.
     Tessa's origins are revealed and her new family of Shadowhunters surrounds her when the well-ordered plan of their lives falls apart. Friendships are tested, loyalties strengthened, and power struggles balanced in this final chapter of the Infernal Devices Trilogy. Young adult readers will enjoy the brightly woven characters and relish the twists and turns of Tessa's epilogue.
