I must have slept awkwardly last night because I woke up this morning feeling as though every muscle in my upper body was full of broken glass, so I haven't been able to do much work but I have been able to read through what there is of the book and sort of mentally gird my loins. I was surprised to see that some of it (although admittedly not a lot) is actually rather good, and I'm sort of worried I won't be able to get back up to that standard, but we'll see.
Anyway, at the moment it consists of about fifty-nine thousand words of bits and pieces and notes and stuff and I'm just going to keep writing until it's finished, however long it takes me. Please feel free to pester me about it; I may need some help getting going in the early stages. I'll keep you posted.
