Summary: Returning to the frozen planet Aren died on was bound to have complications... Major Aren Dalsgaard's newest assignment is to investigate a series of murders on the frigid planet, Drass, where relations between the Treaty settlers and the indigenous inhabitants have taken a nasty turn. A linguist and trained xenologist, Major Dalsgaard should be the ideal Special Investigations Officer for this case, but Drass is where he died, over a hundred and twenty years ago. Sent by his family to the chigyel city, Nyachung finds himself confronted with a murder charge, racial prejudice, and a man who claims to be a hero from his grandmother’s generation. The man could be crazy or he could be lying to manipulate Nyachung, but the sincerity in those spring-green eyes disturbs him more than anything else he's encountered in the foreigners’ city. Evidence that makes no sense, mysterious boxes, and a suspicion that they can't trust anyone in the city drives the major and Nyachung together and out into the wilderness. No one's telling Major Dalsgaard everything, but every step leads him closer to a feeling of imminent catastrophe if he can't wrap this case up in time.

The escape pods fall to Earth one by one over the course of weeks, a mysterious and diverse alien diaspora, each pod containing a different alien race and leaving the world's governments scrambling to deal with this unexpected immigration. Serge Kosygin, still grieving and isolated after his husband's death, watches events with gray disinterest until one day he witnesses a pod crash for himself while driving home. Two of the alien visitors have died, but one survives, badly injured, and Serge is determined that if this alien is also going to die, it won't be under the harsh lights of a government facility. Devastated by the loss of his life mates in their desperate effort to reach safety, the knowledge that Een is the last Aalana in this sector of the galaxy only compounds his sorrow. He wakes in an alien dwelling under the care of one of the native dominant builder species, a being who appears to share nothing with Een besides a bipedal structure. Slowly, with the help of his patient and kind host, he discovers they are more similar than he imagined as they share harmonies and his host assists him with language acquisition. Their tentative first contact soon evolves into a deepening friendship, a balm for two grief-weary souls. They'll need each other and their growing bond for the troubles lurking just ahead.
