Maddy Rupert has a summer job in her dull home town of Hell, Texas. Assisting at the post office, known for receiving very strange letters. People around the world write to the dead, sending last laughs and sad 'told you so's. Maddy's a quiet kid; if grownups want to pay her to drop the letters down a well shaft, she'll nod her head and get it done. An easy, dull summer... till letters start coming up from the well. Addressed to Maddy Rupert.
