Looking at the Amazon reviews and the short excerpt available, I wouldn't hold my hopes up. Sure, they don't mention Babs, but when you have several reasoned 1- and 2-star reviews, the book's not good. The writing in the excerpt also felt similar to the quickly-produced short novels available in newsstands in my youth. Sure, there were some gems in there if you picked the right author (writing in that format is its own talent), but this called back to the poorly-written and poorly-plotted ones.
An interview with the authors discusses Babs specifically, but I'm not sure TKJ is salvagable from its misogynist roots, even if they had Ursula K Le Guin or Margaret Atwood writing the novelisation.
