“Gorgeous, heartbreaking, and ultimately life-affirming,” says Nicola Yoon, #1 New York Times bestselling author of Everything, Everything and The Sun Is Also A Star, of this novel about finding strength and hope after tragedy.

Carver Briggs never thought a simple text would cause a fatal crash, killing his three best friends, Mars, Eli, and Blake. But now Carver can’t stop blaming himself for the accident and even worse, a powerful judge is pressuring the district attorney to open up a criminal investigation.

Luckily, Carver has some unexpected allies: Eli’s girlfriend, the only person to stand by him at school; Dr. Mendez, his new therapist; and Blake’s grandmother, who asks Carver to spend a “goodbye day” together to share their memories and say a proper farewell.

Soon the other families are asking for their own goodbye day with Carver—but he’s unsure of their motives. Will they all be able to make peace with their losses, or will these goodbye days bring Carver one step closer to a complete breakdown or—even worse—prison?
