Book summary

Charlie and Sam are growing up in Marblehead, Massachusetts. One memorable evening, Charlie steals a car, and the two drive down to Fenway Park in Boston for a Red Sox game. On the way home, they are in an accident, and Sam is killed. For 13 years, Charlie meets Sam's spirit in the local cemetery--a tradition that entails a sacrifice for both of them: Charlie works as the cemetery's caretaker, Sam is unable to move up a level in the afterlife. But they both take comfort from the ritual until Charlie falls in love with Tess. But is she alive, or a spirit?
