Jessa Whitworth knew she didn't belong in her ex-boyfriend Caleb's room. But she couldn't deny that she was everywhere - in his photos, his neatly folded T-shirts, even the dragonfly necklace in his jeans pocket . . . the one she gave him for safe keeping on that day.

His mother asked her to pack up his things - even though she blames Jessa for his accident. How could she say no? And maybe, just maybe, it will help her work through the guilt she feels about their final moments together.

But as Jessa begins to box up the pieces of Caleb's life, they trigger memories that make Jessa realize their past relationship may not be exactly as she remembered. And she starts to question whether she really knew Caleb at all.

Each fragment of his life reveals a new clue that propels Jessa to search for the truth about Caleb's accident. What really happened on the night he died?
