Harper Leonard likes to make lists.
1. She has spent her entire life moving from one town to the next, never quite fitting in no matter where she goes.
2. When her family moves to a small town in New Mexico, Harper inevitably runs into Tovido High School's most interesting person: A senior named Oliver who, despite a severe terminal illness, possesses a unique ability to seem... invincible.
3. As she gets to know him, she realizes he is hiding a very important secret to his immortal spirit.
