For your BOOKS directory in the root, this would have you changing your template for send to device to:
Code:
BOOKS/{author_sort:sublist(0,1,&)}/{title} - {authors:sublist(0,1,&)}
Thanks for the quick reply! Your template code worked perfectly. Now both books are where they should be.
By the way, I made a loud chuckle when I read your spouse's book file name.
