How to free a leviathan

"Do you know a fairy with a fever? Or a sasquatch with a stomach ache? Giada Bellantuono is the one to call. She's no ordinary veterinarian. She has the power to heal all kinds of fantastic creatures! Now she and Sinistro, her black cat familiar, have left their home in New Jersey to train with magical veterinarians around the world. And a conference in Argentina has come just in time. A company called C&C Medicinals is kidnapping and hurting magical animals to make medicine for humans! Giada knows firsthand how dangerous the company can be. She saved a unicorn from one of their henchmen just last month. Once Giada gets to Argentina, she'll spread the word. But there's something suspicious going on at the conference, and Giada and Sinistro suspect that C&C Medicinals is at the root of it. Before they can do anything about it, Sinistro is kidnapped! With help from old friends and new ones, including a shy young leviathan, Giada will do whatever it takes to bring down C&C Medicinals and save Sinistro."--
