"Gorgeous, heartbreaking, and ultimately life-affirming." -- Nicola Yoon, #1 New York Times bestselling author of Everything, Everything . Perfect for fans of Turtles All the Way Down , Thirteen Reasons Why, and Zentner's own The Serpent King, one of the most highly acclaimed YA novels of 2016, Goodbye Days asks what you would do if you could spend one last day with someone you lost. Where are you guys? Text me back. That's the last message Carver Briggs will ever send his three best friends, Mars, Eli, and Blake. He never thought that it would lead to their death. 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?
