At the end of Frozen Orbit, Jack Templeton went into hibernation on board the Magellan and launched himself towards the outer reaches of the solar system, in a quest to reach a mysterious object with a strong gravity well. Meanwhile, former crewmate Traci Keene is back on earth in bureaucratic hell. Eventually Jack reaches the object, which is much more mysterious than he suspected. And a rescue mission involving Traci is launched.
While a serviceable sequel to Frozen Orbit, the novel suffers from a less engaging setting. Frozen Orbit was real deep space adventure. Escape Orbit has too little deep space and too much bureaucratic machination. The real action doesn’t start until well into the second half of the book. The AI elements are interesting but not groundbreaking.
