That is, until the Hotel Magnifique comes to town. The hotel is legendary not only for its whimsical enchantments, but also for its ability to travel—appearing in a different destination every morning. While Jani and Zosa can’t afford the exorbitant costs of a guest’s stay, they can interview to join the staff, and are soon whisked away on the greatest adventure of their lives. But once inside, Jani quickly discovers their contracts are unbreakable and that beneath the marvelous glamour, the hotel is hiding dangerous secrets. With the vexingly handsome doorman Bel as her only ally, Jani embarks on a mission to unravel the mystery of the magic at the heart of the hotel and free Zosa—and the other staff—from the cruelty of the ruthless maître d’hôtel. To succeed, she’ll have to risk everything she loves, but failure would mean a fate far worse than never returning home.

Ellingham Academy is a famous private school in Vermont for the brightest thinkers, inventors, and artists. It was founded by Albert Ellingham, an early twentieth century tycoon, who wanted to make a wonderful place full of riddles, twisting pathways, and gardens. “A place,” he said, “where learning is a game." Shortly after the school opened, his wife and daughter were kidnapped. The only real clue was a mocking riddle listing methods of murder, signed with the frightening pseudonym “Truly, Devious.” It became one of the great unsolved crimes of American history. True-crime aficionado Stevie Bell is set to begin her first year at Ellingham Academy, and she has an ambitious plan: She will solve this cold case.
