The heart-breaking and at times humorous look at one teen's life after the death of his best friends and how he navigates through the guilt and pain by celebrating their lives—and ultimately learns to forgive himself.
     What would you say if you could spend one last day with someone you lost?
          One day Carver Briggs had it all—three best friends, a supportive family and a reputation as a talented writer at his high school, Nashville Academy for the Arts. The next day it all crashed and burned, literally, after he wrote them out of existence with an inane text sent to his friend Mars—the last words his friends ever see. Carver can't stop blaming himself for the fatal crash and he's not the only one. Eli's twin sister is trying to freeze him out of school with her death-ray stare. Even worse, Mars's father, a powerful judge, pressures the district attorney to open a criminal investigation into Carver's actions. 
          But Carver has some unexpected allies: Eli's girlfriend, who is the only person to stand by him at school, and Blake's grandmother, who asks Carver to spend a Goodbye Day with her—having him stand in as Blake for one last day doing all their favorite things so they can share memories and say a proper goodbye. 
          Soon Eli and Mars's families are asking for a 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 prison or a complete breakdown?
