In 2013, Heimerdinger posted that "For months I've told fans that the new Tennis Shoes book would be called Thorns of Glory. Most know that this book is long enough that my publisher will likely divide it into two books. I've presumed it would be Thorns of Glory Part 1 and Thorns of Glory Part 2, sort of like the Feathered Serpent books. HOWEVER, I think I've come up with a better title for the first of these 2 books: Drums of Desolation. Let me know what you think. Just know that Book 13 is likely still called Thorns of Glory."
