Diane Duane asks if you'd like to buy a sequel to 'The book of Night with Moon' and 'On Her Majesty's Wizardly Service':
She's asking again now: http://outofambit.blogspot.com/archives/2006_02_01_outofambit_archive.html#113999576226329078
send her an email if you would buy the book.
Just sent off my request as I really liked the first two in the series.
Of course, having repeated it here it will turn out that we have a bigger friends list overlap than I think. :-))
