Looking for that specific interactive scifi book

I remember reading that book 20 years ago but I couldn't remember the title. All I remember is that it was interactive and at the end there are choices, like for example if i want to go that way go to page 76, if not go to page 50 and depending on the choice, i may have a good or bad ending. It was scifi, spaceships and aliens, exploration. I vaguely remember i think there was a callahan on its title, not sure. Can anyone help me find that book?
