The One-in-a-Million Boy by Monica Wood

 Ona Vitkus, age 104 and cranky, has come to look forward to the young Boy Scout who comes every Saturday to do things around the house.  She finds his obsession with entries in the Guiness Book of World Records intriguing - even more so when he seems determined to find a way to make sure Ona becomes a record holder.  Then one day, the boy's father, Quinn, shows up to do his chores.  Quinn, a hardly successful musician never quite warmed to his son - this odd boy who counts everything; who has a freakishly good memory; who has died.  Ona and Quinn eventually form a bond over the memory of "the boy".  Both look for a way to grieve the boy's death and a way to honor his life.  The choices they make about how to do either drive this sometimes humorous, often thoughtful story.  Something about each character puts them outside the "normal" box but they eventually confront the reality that no matter how odd we feel or how odd we appear, we all struggle to find connections.
