Enemy Within : After a stint in an alien prison, Captain Ari Rose wonders why she even bothered to survive. Stripped of her command and banished to her father's scientific expedition to finish a Ph.D. she doesn't want, Ari never planned to languish quietly behind a desk. She wasn't built for it, either. But when pirates commandeer her father's ship, Ari once again becomes a prisoner. As far as pirate leader Cullin is concerned, Ari's past imprisonment puts her dead center in Cullin's sights. If she hasn't been brainwashed and returned as a spy, then he's convinced she must be part of a traitorous alliance endangering billions of lives. Cullin can't afford the desire she fires within him and he'll stop at nothing, including destroying her, to uncover the truth.
