The Disappearing Otters (Seaside Sanctuary)

Elsa Roth's life at a seaside marine biology facility is about to change. There are new arrivals at Seaside Sanctuary: a group of river otters. But the adorable animals aren't the only newcomers; a new group of volunteers is also starting at the sanctuary. When a new boy named Anson shows up in the group, Elsa is less than thrilled. He's nothing but rude and doesn't seem at all interested in animals. But soon Elsa has bigger problems on her hands. One by one, the otters start disappearing. Can Elsa get to the bottom of things before more animals go missing?
