Master Negotiator Riley Smith is a man on a mission, not the way he wants to spend the Yuletide holiday. He tries to make the best of it by flirting with Karma Engineer Pax, but the sexy Kar-En seems more interested in Yanar Aht, the mission's top translator, than him. Yanar knows how to say yes in just about every language in the civilized Romba Galaxy, but he never gets the chance. His harmonic body longs to find the heart-mate who will drive him to sing the Song of Fulfillment, a seeming impossibility on a ship full of humanoids. It definitely puts a sour note in his holiday spirit. As the ship is on the verge of flying apart, killing the entire crew, Pax must choose between duty and her growing love for these two men. She suspects carrying a cargo load of immature chaos balls would be easier. But Fate has a karmic gift in store for her… if she’s brave enough to accept it.
