Ptolemy Grey is ninety-one years old and has been all but forgotten-by his family, his friends, even himself-as he sinks into a lonely dementia. His grand-nephew, Ptolemy's only connection to the outside world, was recently killed in a drive-by shooting, and Ptolemy is too suspicious of anyone else to allow them into his life. until he meets Robyn, his niece's seventeen-year-old lodger and the only one willing to take care of an old man at his grandnephew's funeral.
