I haven't read the one you got for HD Holidays, but I'll put it on my list of Things To Read. :) Actually, there, I've only read the one for Emma. H/D is my OTP, too, so I can vouch for you liking this fic, I think! It's definitely the primary pairing. :) It is long, but it's not a fic you have to plough through, you know? It's very handle-able, heh. :)

I can never guess at this kind of thing!!! Ask Rachel; it totally sounds like she knows! :P
