The Lady really isn't in the first few books that much but if Croaker is wrong then the whole thing will be crap. I will also be interested to see who plays Raven and Goblin. This is one of my favorite books series, or at least the first four were, so I will give it a chance either way. I am not a purest and I expect and adaptation and not a literal reproduction but it needs to feel right and if those three are not right it can't work.
One of the first screen names I used on the original site was Toad Killer Dog.
