I found it today.
You know, that elusive creature we writers are always searching for, then clinging to for dear life. Sit in the sun for long enough in enough cafés, do enough writing prompts, and apparently it comes to you. The opening page of Inevitable now sounds like it was penned by the same person who wrote "Destined for Greatness" and "The Ghosts of Christmas Past" and "After LA".
So, it really works. Keep writing! Keep practising. It will come.
And it's a great moment!
Just need to do the other 299 pages now...
