Felix and the Hidden Treasure

Convinced that his father, who disappeared at sea two years ago, is still alive, 12 year old Felix embarks on a search for him in the company of Old Tom, a retired fisherman Squawk, a thieving one legged parrot and Rover, a cat who acts like a dog. Their journey takes them to Darkshadow Island, where a secret community inhabits an underground city, ruled by the megalomaniacal Morgäa possessor of a priceless treasure.
