The Mandala Maneuver by Christine Pope
Alexa Craig is well aware she's known as "The Ice Queen" -- and not out of admiration -- but her reputation has served her well in her diplomatic career. Alien ambassador Lirzhan understands his people are viewed with suspicion and curiosity by the members of the Gaian Consortium, but the Zhore do not casually reveal themselves to outsiders -- not even to someone as intriguing as Alexa Craig.
But after their ship is attacked during a routine flight, the two strangers must rely on each other to survive on the supposedly uninhabited world where their escape pod has crashed. When Alexa and Lirzhan discover the secret hidden behind Mandala's wild beauty, they must put duty before desire and risk everything to warn the Galactic Council of a conspiracy that could endanger their lives, their worlds, and the future they have begun to imagine together.
