Why start off at Chapter 5? Not knowing what the missing chapters contain, I will say I've been able to pick up the thread from the pitch and what's here. There are still some little quirks in the dialogue and the way you move the characters around. One downside comment - example being the opening of chapter 12 - is that there are times when you pass information to the reader (the first paragraph) and then repeat it a little in the dialogue between characters (Michael and Tessa Marmion.) It is bound to be smoothed out in the edit, but worth having a look as you go. As for the storyline? There's certainly a good story here, but don't be afraid to let your characters have emotions now and again, and to open things out a little more. Read and enjoyed, backed, and would like to see more when available.
