On Monday 20th June 2015 'Out of Time' will be released on kindle. The following Monday the paperback version will be released. It has been a great couple of years continuing the series, and then finishing the fourth and final book.
'Out of Time' is my favourite of the four books. I thoroughly enjoyed writing it and completing the plans that I had first written seven years ago. I am sure you will enjoy the exciting adventure and the twists and turns on the way to big finale.
