(3.5 stars) Great writing and character psychology, but it feels a little aimless. The entire book rests on the interactions between two characters, which begins strongly but eventually gets a bit claustrophobic. The story drags a little in the middle: once the characters are ejected from the spaceship, it becomes "teens on the camping trip from hell," which didn't quite feel like it needed the awesome sci-fi beginning to work. 
 Minor side note: I'm disappointed that we never hear the full story behind Tarver's status as a war hero...! 
 For those of you who have watched Farscape...(view spoiler)[ 
 ...the "perfect replica of my lover" story rings a bell.
