"Everypony thinks they know Lyra. Bon Bon only wishes she could say the same. For two years she has tried to get to know to the unicorn, but Lyra refuses to show her true self or accept Bon Bon's advances. When Bon Bon discovers that Lyra is leaving town without so much as saying goodbye, the earth pony decides to leave everything behind and follow, no matter how far they must go or how hard Lyra protests.
"An uncommonly tight-lipped Rainbow Dash tags along as a guide, paid by Lyra for her services, but the young Wonderbolt appears to have her own motivations as well."
