File 1 Book - Genealogy Ancestral Ahnentafel (Register) Report for Father, index
File 2 Book - Genealogy Ancestral Ahnentafel (Register) Report for Mother, index

What else did you want to put in your book? Stories? Maps? Photos?
When you say book, are you referring to the Book capability of FTM?
Have you thought about combining the two files, just for reporting purposes. (Actually, leaving them split probably makes more sense to keep the Mom's side and Dad's side separate.)
