Mixing First and Third Person
I'm clear on the differences, pros and cons, between first and third person writing. But what about a Prologue written in first person, and the rest of the book written in third person? William Goldman used this approach in "The Princess Bride", starting with his search for the (imaginary) classic by S. Morgenstern, and then moving to the story told in third person.
I have an Epilogue that ends with the boss of the main character taking a photograph of her in her late 20s. I want to write a Prologue in first person about her son receiving the photo from a relative, a photo he has never seen, after her death at age 88.
I know William Goldman can get away with this, but would an agent or publisher reject the book by a new author based on mixing first and third person?
Have you written in this way?
