OK, try something different -- Has she read For Yourself? There is also For Each Other.
Another thing to try is Tantric Sex with is NOT O-focused. I had a book that started just with breathing exercises. I can't remember what it was. (I actually really tried in my XM to improve our SL, it just never went anywhere.) XH and I got through the first few chapters, but I got tired of pushing and wanted him to get us through the work. I didn't want the burden of guiding us through it, if that makes sense.
Anyway, it was a pretty non-threatening, loving book that I THOUGHT would help us because it takes away all the O-pressure and puts women out of the standard man-pleasing role that I think it is hard for men to grasp.
