Violeta Volcán y el tesoro de William Winter

Violet is an extremely intelligent and curious girl, which makes it difficult for her to connect with people her own age. This, combined with her explosive temper, leads to more than one argument and unpleasant situation, earning her the nickname Violet Volcano. During an outing that was supposed to be a family trip but turns into a reunion with her classmates, Violet ends up in a secluded sea cave. Just as she realizes there's another boy with her, a wave crashes down and swallows them both. Thus begins an incredible adventure filled with pirates, treasure, and a round trip through time.
