The three books are tentatively slated to ship in consecutive months starting in October 2016. More details, including the individual titles, to come in the months to follow. But I can say now that the Prey story has all that I love about Trek in it, and that I'm thrilled to have it on the slate at the close of Trek's 50th anniversary year and next to the start of The Next Generation's 30th anniversary year!
In the meantime, you can check out my current Trek novel, Star Trek: The Next Generation: Takedown, now available. Engage!
