I have just realized that Jane, from Shades of Milk and Honey should participate in the Month of Letters Challenge. So, she is.
If you want to write to her, address correspondence to:
Mrs. David Vincent
P.O. Box 221298
Chicago, IL 60622
I will tell you, as a teaser, that she will be writing back to you with an actual quill pen on a writing slope from the 1800s. The letters will be “Real time” for her in that they will be coming from February, 1815. This means that they will contain references to the first chapters of Glamour in Glass and definite spoilers from Shades of Milk and Honey.
