Amazon has the preorder for the hardcover book Twin Peaks: The Final Dossier by series Co-Creator Mark Frost, for 13.43. The price has been steady for a few weeks, but posting in case it may rise, was $19.79 before the drop earlier. Didn’t see it posted anywhere here. Book appears to be a canonical sequel to the current new season.
