This week, an experiment gone wrong sends the Enterprise back to when dinosaurs ruled the earth. But when they discover that this Earth got through puberty without a crater face, it’s off to the Guardian of Forever to set right what once didn’t go wrong. What does an injured Captain Kirk bring to a story’s table? Are Starfleet officers aware of what they’re signing up for? Is Diane Carey, for that matter? All this and more in First Frontier, the book that doesn’t go as all in as you would hope.
