Wings of fire: Secret of the Emerald Amulet

Porpoise lives a pretty normal life in the kingdom of sea, until her fourth birthday, in which she inherits an Emerald Amulet from her parents. The next day, her parents vanish without a trace, and no one in the town, or anywhere else, for that matter, remembers that her parents even existed except for her. Even her own sister doesn't remember her parents! To get rid of her and her sister, Seaweed, (because the orphaned street urchins were considered a nuisance) the dragons of the town send them to Jade Mountain Academy. Porpoise has to battle against enemies, crushes, and the hardships of friendship, all while trying to find out the Secret of the Emerald Amulet.
