So we love all of Luke's stuff. We have shelves dedicated to the different serieses. Was the 5th book a backer only option? There are none in stores, on Luke's website, amazon, nothing. Was the book not produced large scale? Any info or tips would be appreciated. If Luke happens to see this. Thank you for the years of reading listening, and other worldly joy you bring to us all.
