Coming in the last three months of this year is John Jackson Miller's new trilogy, Prey, which has been previously announced as a TNG book featuring the Klingons. Well now Clark tells us there's much more to it, as Prey is the next big 24th century crossover:
We have the Titan being recalled from their mission, we have the Enterprise-E, there's some involvement with some Deep Space Nine characters. So it is a Star Trek: All series; if you can do a three book series, you should be able to take out all the pieces, including the sharp knives, and play with them all.
Since it is the fiftieth anniversary, Captain Kirk makes a guest starring appearance in one of the books.
