The Wildes: The Vaquita: The Vaquita (The Wildes, 2)

Ring and Asia Wilde's wild life is anything but ordinary. Instead of attending school, they travel the world with their tutor and parents (scientists who work to protect endangered species). On their last adventure, they swung through the Amazon rainforest to save their mom from vile kidnappers--while defending the forest's population of golden lion tamarins. Now they're in Baja, Mexico--the Sea of Cortez to be exact--searching for the endangered vaquita and finding danger and conspiracy instead.
