Months after catching a common virus, twelve-year-old Ivy still hasn't recovered.

Ivy doesn't even have the energy to play music. Hoping a change of scenery will help, she's spending the summer in North Carolina's Blue Ridge Mountains, where her uncle has converted an old house into a bed and breakfast. The Everly House has a long history--including a stint as a sanatorium, a treatment center for tuberculosis patients, in the 1920s.

Ivy starts having dreams about a girl named Jessie Pearl, a TB patient who stayed at the house a hundred years ago. Like Ivy, Jessie was an adventurous musician who struggled to adapt to her sickness. But at the Everly House, she was able to rest, listen to her body, and find new ways to fill her time.

As Ivy delves into the history of the house, hoping to find out what happened to Jessie, she makes other discoveries that turn her summer in the mountains into a new beginning.
