All I can say is... I'm working on it right now and it's still a little while off yet.
Haven't got a specific release date because it's still in progress.
And I'm still working on a title... I've got a few in mind. But it's hard to narrow it down.
I've also been working hard on another project (Wasteland Wonderland) at the same time as I've been writing book 8... which is another reason for the delay. Probably, definitely the main reason...
Anyway, wish me luck. Hopefully i'll have Book 8 finished sooner rather than later.
