Yes! I remember seeing the Hilary Clinton/Louise Penny novel and thinking it seemed sort of unnecessary. Both obviously accomplished in their own fields, but did we really need them to join forces?They are all at it. Writing books with prolific writers. At least it's very clear they aren't solo writing the book. Unlike all the ones that are ghostwritten and not made clear. Even if I don't think they write much more than an idea and some subject specific knowledge.
The one Dolly Parton did with James Patterson was turgid mediocre rit.
