I wrote that penultimate book for the series and finished it at the end of last year. On January 1, I started work on Book 6 of the Dream series.
Then I got derailed -- long story, but a perfect storm of stuff happened. A major event I was managing took place, my sister needed my help, my mother-in-law passed away, I got majorly sick.
But I'm back on pace now, and hope to finish Book 6 of the series by mid-year. Then on to Book 7. Books 8 and 9 next year and ...
Who knows what's after that?
