"Oliver is a sea otter determined to prove that he's not a momma otter's boy. In an effort to show his bravery, he swims into Puget Sound where all the ships and humans are. That's when disaster strikes: An oil spill threatens the local wildlife -- and it traps Oliver in the harbor! Franklin, an excitable dachshund puppy, is also lost. He's been separated from his owner, Lucy, and he has no idea how to get back to her. Now Oliver and Franklin must journey through the Pacific Northwest wilderness in search of their families. Along the way, they'll discover exciting adventures and meet new friends -- but will they be able to find their way home?"--Publisher.'
