From the New York Times–bestselling author, this contemporary YA novel follows a girl as she navigates secrets, romance, and danger in an aging grand hotel.

Way up in the Swiss mountains, there's a hotel steeped in tradition and faded splendor. Once a year, when the famous New Year's Eve Ball takes place and guests from all over the world arrive, excitement returns to the vast hallways.

Sophie, an intern at the hotel, is tasked with ensuring everything goes as planned. But the unexpected seems to lurk in every corner, and she soon realizes that not all the guests are as they appear to be. Finding herself embroiled in a thrilling adventure, Sophie risks not just her job but her heart . . .

"A Castle in the Clouds is a rollicking, non-stop romp full of characters and character, and it kept me smiling all the way to the end." ―NPR
