The Keys to Prime's Gate

Nyx is a regular 9th grader going through the boring aspects of life, that is, until she is handed a special set of keys. Her Grandpa is part of an organization called The Keepers who each protect fictional worlds and keep their story in order like it should be. But a greedy man is trying to destroy the Keepers and take over all the keys, wanting the stories to play out like he wants them to. Nyx is handed the keys of Prime's Gate, or the Hub series: Transformers Prime, because her Grandfather is nearing the age where he can't protect the world anymore. The brunette girl is determined to keep the world safe and her friends in it from evil and maybe stop the man who wants the worlds along the way.
