Summoned to Folio, she must rescue a missing prince, helped only by her pet hamster and a malfunctioning robot. Their mission to the Frozen Sea will bring them face-to-face with a danger both more deadly and more magnificent than they ever imagined. What Jewel discovers will change not just who she thinks she is, but who we all think we are...
