Delphi Challenge, book nine, is coming out on Jan 5th.  It's available for preorder now.   The next book Delphi League is at the Editors.

I'm actually working on book four of the Stone Series.  I've got a beginning, middle, and end, but now I have to write all the parts in between.  It was really hard to switch series.  It took three weeks before I quit writing the Delphi Series in my head.  I hope it doesn't take that long to switch back.
