Actor David Ajala, joins the season three cast as a brand new character, Cleveland Booker, a.k.a. Book. He made his Star Trek debut on this panel. The character he plays is, of course, Smart and capable. Book has a natural charisma and devil-may-care attitude that tends to get him into trouble as often as it gets him out. Sounds an ideal companion for Burnham!

CBS released seven pictures of the two characters, in what looks like the Iceland location, that accompanies this article.
