Nice little Alysha Forrest story - she's still an ensign, assigned to a diplomatic escort that turns out to have unexpected complications, like a city that consists of platforms on pillars so tall the ground is all but invisible...and a lieutenant who discovers a severe case of acrophobia when she arrives there. Unlike the other two Alysha books I've read, there's no antagonist here - everyone is working together to make things go as well as possible given the circumstances. An interesting set of characters, some of whom we may see again - there's some comments that might (or might not) be foreshadowing. Excellent, as usual. ( )
