Stephen Graham Jones "Mapping the Interior" PDF

Walking through his own house at night, a twelve-year-old thinks he sees
another person stepping through a doorway. Instead of the people who
could be there, his mother or his brother, the figure reminds him of his
long-gone father, who died mysteriously before his family left the
reservation. When he follows it he discovers his house is bigger and
deeper than he knew.
The house is the kind of wrong place where
you can lose yourself and find things you'd rather not have. Over the
course of a few nights, the boy tries to map out his house in an effort
that puts his little brother in the worst danger, and puts him in the
position to save them . . . at terrible cost.
