Allegory in 'Oranges Are Not the Only Fruit'

How does Winterson’s use of fairy-tale/allegory add to our understanding of ‘Oranges are Not the only Fruit’ as a whole?

‘Oranges are Not the Only Fruit’ is a novel which often uses allegory to create depth and meaning to the novel by blurring the line between fact and fiction. The use of allegory adds to our understanding of ‘Oranges’ as a whole in many different ways.
Allegories are used within ‘Oranges are not the Only Fruit’ to fragment the text; the fragmentation is a key characteristic of post-modernist works. This use of fragmentations helps the reader to look deeper into the myths and fairytales to better understand the novel’s main plot and to highlight Winterson’s post-modernist ideas.

The “rebels” represent her exploration of her sexuality and the new emotions it brings, which may cause her to lose much of what has shaped her for many years but will also allow her to become the person she longs to be.
