Now that's a very poignant and sad bit that leaves you feeling rather sorry for Parvati.
I'm not sure what to tell you about dealing with writer's block, I seem to have a long-term case myself. One thing that's helped, some, is working other stories around it and letting that help weaken/soften the block.

Thanks for the advice. I'll try it out. I do think you're being soft on Feathers and Gilt, though, just because I'm being an angst-muffin at the moment. ^-^
