Leah Tang is off on her second mission as a rookie Genrenaut, this time to repair a breach in the Science Fiction world. A peace treaty is due to be signed, a boon to life, limb, and trade in a good part of this genre world, but an ambassador who has played a critical role has been kidnapped. If he isn't present for the signing, many of the other intended signatories will back out, because he's the one they all trust. Leah learns a lot about a world that shouldn't exist, a genre she though she knew, and her new colleagues.
She also teaches her colleagues something about the value of lacking preconceptions, otherwise known as significant prior knowledge. Along the way, we get hints that one of those colleagues is something other than what he outwardly seems, too, though everyone agrees Leah isn't ready for that knowledge.
Once again, a lot of fun. Well worth your time.
