All You Need Is Lung by Sharon V. Agar

Fiona has always thought of herself as a straight shooter. She believes you should play the hand life gives you with integrity, and handle the outcome with good grace. But then she receives a death sentence—a slow suffocation as her lungs gradually turn to scars. With so much of her life unlived, she is unwilling to accept this fate without a fight. All You Need Is Lung is the story of Fi’s search for life, in the form of new lungs from a donor. To do this, she must navigate the overtaxed and complex organ allocation system that will determine whether she lives or dies. The physical and moral journey she undertakes, the things she discovers about herself and others, and the impact on what used to be her world, will change her for as long as she lives...however long that may be.
