This historical fiction middle grade book was excellent. Set in the 1930s in New York, the book starts when 10 year old Halle's mother comes down with tuberculosis (also known as consumption). Tuberculosis was the leading cause of death in the early 1900s and many people were afraid of getting it. There was no known cure in the 1930s and antibiotics did not exist yet. Halle's mother is sent to a sanatorium to recover, with a treatment focus of sunlight and fresh air. When Halle also becomes ill, she is admitted to the children's wing of the sanatorium.

I was captivated from the start and finished this in one day. Halle was a tremendous main character - courageous, empathetic, scared, and tenacious. Her relationships with each of her parents were an important part of the story, as well as the friendships she gained while at the sanatorium. 

A touching and informative historical fiction that was riveting and hopeful. Recommended for ages 9+.
