Another fan told me that Roger Davis confronted KLS about some of the stuff that she wrote about him; probably the Maggie's diary section of the movie book. She didn't deny writing it, not that she could. But she did tell him that she didn't think that it was that bad.
Maybe she was less than discreet about sharing her experiences with Roger, maybe she wasn't. But I really have a difficult time picturing him as the wounded party, as his reputation does precede him. KLS is hardly the first one to have issues of with Roger but she was probably the first to put it in print.
