It's A Small Galaxy by Russ Crossley

In the future cloning becomes child's play. When his father brings home a science e kit from an alien world when he was ten years old, young Bernie Culpepper clones a Bigfoot which he names Shakespeare.

Now forty years later Shakespeare may hold the secret to change lives and save a father's life. But before he can Bernie and Shakespear must find a man presumed missing long ago.

A tale of the future where the galaxy itself is smaller than ever.
