Trixie's showpony act is just that--an act. Dissatisfied with her lack of power (and inability to live up to her late mother's hopes for her) she seeks magic relics and objects. Her search leads her back to her late mother's collection--but there's a catch. The collection is in the hooves of her estranged father and his new family.

Trixie must face her past, her father, a newly discovered sister, and the Everfree Forrest on her journey towards being "Great and Powerful".
