Lane is seventeen, and is just moving into Latham House, a sanitorium for total drug-resistant tuberculosis afflicted teens. It's an interesting and unusual scenario, and really treats the disease seriously--this is no incurable movie disease.
He meets Sadie and falls for her and her quirky group of friends. Sisman gets teen humor perfectly right--the near constant sarcasm, teasing and jokes (and it's actually funny) and yet the book is poignant without the slightest trace of treacle. Fabulous.
