As part of the structure of When Skies Are Grey I introduce a series of letters signed by 'Mother'.
There are eight letters from Mother, mostly found in the first part of the novel. I use these letters as a means of plot development but also to create an element of intrigue for my main character.
The use of letters in a novel can be a very handy device for writers. In the Colour Purple by Alice Walker, letters were used as part of the narrative. Each one starting 'Dear God'. The letters carry the narrative when two main characters are separated from each other, allowing the author to be in two places.
In When Skies Are Grey the purpose of the letters is really for dropping hints and making suggestions about things to come. Hopefully enticing the reader to stick around for the revelation.
If you've ever used letters in your writing, how did you use them and why?
