North of the Fangs was where all the best stories and worst monsters came from...and that’s where Seven was. Twelve is a Huntling. She gave up her name and identity to train in the art of fighting monsters—but while her fellow Huntlings train to keep the peace, Twelve secretly builds her skills to take revenge on those who murdered her family. Then her new home is attacked, and all her plans are thrown into chaos. Her mentor is killed, and a fellow Huntling named Seven is captured. Twelve decides to rescue Seven alone—but unexpectedly finds herself joined by two classmate rivals and an ancient stone guardian named Dog. To save Seven, Twelve and the others must face new enemies and old terrors alike on a treacherous journey—one that will lead Twelve to discover dark truths about her world, her powers, and the past she has so desperately tried to hide.
