It all began with a strange, mysterious correspondence left for authors Tony DiTerlizzi and Holly Black at a small New England bookstore. Written by three siblings, the letter told of their great-great-uncle Arthur Spiderwick and an unfinished tome filled with eyewitness accounts of creatures otherwise thought to be the stuff of legend. In the #1 New York Times bestselling serial the Spiderwick Chronicles, readers were enthralled by the account of the those siblings, Jared, Simon, and Mallory Grace, as they battled dwarves, goblins, elves, and a diabolical ogre in their efforts to hold on to their uncle Spiderwick,s life work. Now, through the combined efforts of the Grace children and authors Tony DiTerlizzi and Holly Black, Simon & Schuster is thrilled to present that work to you!
