16 parts Ongoing After losing the love of his life in a subway explosion, 27-year-old Dan is haunted by grief, guilt, and fading memories. When a carefree, younger student named Donovan barges into his life-and refuses to leave-Dan tries to push him away.
Then comes the diagnosis: a terminal brain tumor, six months to live, and the cruel erosion of memory.
As Dan forgets the past, Donovan becomes his present-but he's hiding a past of his own. And as snow falls over New York, Dan must decide whether to keep chasing a ghost... or take a chance on the boy who promises to remember everything for them both.
