A listing on amazon.ca and other amazon outlets for Star Trek Prometheus - Fighting Fire with Fire by Christina Humberg and Bernd Perplies indicates that Titan Books has secured the English Language rights for the Star Trek Prometheus trilogy originally published in German last year by Cross Cult. The title is listed for November 28th 2017.
There are no listings for this book on any of the either online retailers as far as I'm aware and listings for the other two books are nowhere to be found, but I would be surprised if the other two wouldn't be released rather soon after the first book.
If you are unaware of the Prometheus trilogy: Cross Cult, the publisher of the German translation of Pocket'sStar Trek novels published an original German language Star Trek trilogy set after the "The Fall" novel with an original crew onboard the U.S.S. Prometheus. You can find the covers and translated blurb from the German version by clicking on the Prometheus label on the right or just here.
