Glad you liked it. Always a fear I have used up my best ideas but a little break and doing other things helped me a bit. There could be a few interesting plot twists in a post tf story, we'll have to see.
Lucas being an angel in this world though is not simply an angel changed. She could be the physical embodiment of what an angel is... A prime template essentially. So if something did happen to her, the idea of Angels- and angel transformations wouldn't exist... Just as a thought given she may well be 'the first' angel in this tale...
... She already has a church and people who believe in her after all ;)
Guess there's still more to the deep hole to keep digging ;)
