*claps loudly* This was an afternoon well spent! I love AU's. This was perfect. I'll admit it took me a whole read through to figure out the letters bit. I can be a little slow on the uptake sometimes.
Everything was so well done. The whole storyline hooked me right from the start. There were times I didn't want to keep reading for fear of what would happen next. But I put my fingers in front of my face and trudged on. I am very glad I did!
