Twelve-year-old Josephine Russing lives alone with her father. Mr. Russing is a distant, cold man best known for his insistence that every member of their town wear gloves at all times, just as he does—even at home—and just as he forces his daughter to do as well. Then one day Josephine meets a boy named Fargus. But when she tries to follow him, he mysteriously disappears and Josephine finds herself in another world called Gulm. Gulm is ruled by the "Master," a terrifying villain who has taken all the children of Gulm. With Fargus by her side, and joined by Fargus's friend Ida, Josephine must try to find her way home. As the trio attempt to evade the Master, they encounter numerous adventures and discover the surprising truth about the land of Gulm, and Josephine's own life back home.
