Bestselling author Theodore Gray received a remarkable email: an 11-year-old reader had just been awarded a National Award from The Library of Congress' "Letters For Literature" for a letter he wrote to the author about his book, The Elements.  Every year the Library of Congress runs a competition for school kids to write a letter to their favorite author and explain the impact that a book has had on the student. The author's response and student Xander S.' letter can be read here.  Gray says: "This really is pretty much what authors live for (that and the royalty checks)."
