IDW, you mean.
The story is an epilogue to the movie and will appear in the regular monthly Star Trek book in issues 21-23.
The solicitations for issues 21 and 22 are more than a little vague about the storyline. I'm curious what the solicitation for issue 23 will reveal...
Okay, okay, probably not a lot, since that will be made public in about two weeks -- and the movie's still a month-plus out.
