Sequel to A Favor For A Friend Continuing the story of Major Jake Archer and Captain Bart Hilton who first appeared in A Favor For A Friend (Other Worlds #1), and who are now a committed couple. On a mission with the rest of their team surveying a series of ruins, Bart and Jake have yet another disagreement when Jake refuses permission for Bart to investigate certain of the ruined buildings. A disgruntled Bart decides to disobey the major and enter a ruin he is particularly interested in, believing it will reveal something of the language of the long disappeared inhabitants. Bart soon realizes he has made a mistake when he becomes trapped underground with no-one knowing where he is, and he is then subjected to a cave-in, and this time Bart doesn’t believe he has any chance of being found, let alone being rescued. When Jake returns from his patrol and can find no trace of Bart he realizes that the captain has disobeyed his order. Jake’s anger at his lover’s action is short-lived when Bart cannot be found. Jake summons the other members of the team and a search begins. Eventually, Bart is tracked to one of the ruins but there is still no trace of the man himself, but there is evidence that something happened inside the ruined building, the clues suggesting Bart was somehow caught below ground. Knowing they need help, Jake contacts the Alkya base and an engineering team is sent to assist Jake’s team in a rescue attempt. Jake is fearful they will not be in time.
