Sir Lionel Frost is a brave and dashing adventurer who considers himself to be the world’s foremost investigator of myths and monsters. The trouble is, no one else seems to agree. He sees a chance to prove himself by traveling to America’s Pacific Northwest to discover the world’s most legendary creature: The Missing Link, a living remnant of Man’s primitive ancestry. Mr Link is the slightly silly, surprisingly smart, and soulful beast who Sir Lionel discovers . As species go, he’s as endangered as they get; he’s possibly the last of his kind, he’s lonely, and he believes that Sir Lionel is the one man alive who can help him. Together they set out on a daring quest around the world to seek out Link’s distant relatives in the fabled valley of Shangri-La.
