Because of the way L to E is written - mostly in the form of letters and a few journal entries - I didn't think it would work as a full length novel. It has a story, but it's not standard narrative. I was very limited in what I could tell, what could Peter could know and do. I tried out a couple different ways of writing it, including juxtaposing Peter's letters with a third person narrative about him. But in the end, I decided the letters alone were the best way to work it.
The main purpose of this is to give more insight into Peter, and to give Peter fans a chance to spend a bit more time with him. It also helps tie in some ideas that will come into play in the final book in the My Blood Approves series.
Since it's shorter, I want to add some other bonus content. So, what kinds of stuff would you the reader like to see as bonus content to go along with Letters to Elise?
