An announcement regarding Hidden: Book 4

I've put this post off for far longer than I should have done, but I can't delay any longer. So, here goes...I'm having to delay the release date of the fourth and final book in the Hidden series.When I released Reaper's Rhythm: (Hidden: Book 1) at the end of July 2013, I was confident I could deliver the rest of the series at a pace of one book every six months.
