I can see the film sequence too. We have all seen something similar many times in the movies. It is the proper ending for a light popular romance. Unfortunately Mandy Sayer gives us a coda in italics, seeing it perhaps as an opportunity for some 'fine writing', or the obligatory happy ending, the triumph of love and sex. But the introduction of a new character, her husband Yusuf, at this late stage, without much preparation, is a bad mistake.
Sex is always a difficult subject to write about without sounding salacious or coy.
According to the accompanying blurb, Dreamtime Alice has already been sold overseas and we will eventually see the movie version. I am not surprised. I hope they leave out the last nine pages.
