To update you on where they are, this was from Forbidden Planet bookshop in London (England) who have them in stock (unlike Amazon UK who are still saying "we'll notify you when it comes out"). To Be Read when I have finished rereading Diane Duane's Rihannsu subseries so probably before or at the weekend (I force myself to only read one book at a time these days, otherwise I tend to do "ooh, shiny!" and keep picking up new books and never finishing them)...

I assume that the seven books are Fledgling, Saltation, Mouse and Dragon (is that the official title now?) and the Omnibi, or have I missed something else?
