Polly Pippin and Devil's Hole Island

An island suddenly appears off the coast of the Bahamas. Lord Knightly guardian of earth for the Freeflyers, asks Hamish and Ape (acronym for Algernon Ponsenby Eagles) co-pilot and friend, to take technical equipment to the island. Polly, Alison, India overhear what the Lord has said and with Fifi the dog, stowaway on the plane. The added weight causes Hamish to ditch on beach on the island. The Lord sends Piers and Miles to the Island in his yacht to rescue Hamish and Ape. Miles sister and Lily and Lucy also stowaway on the yacht and the boys are furious and worried for their safety. The Rebels Capture Miles and tell him to get Polly and Alison or they will kill Piers, his sister and Lily and Lucy. They go ashore, and the Island starts to sink. The girls are captured by Zack and taken to his earth home. The boys end up getting washed out to sea for the shark’s lunch.
Hamish and Ape have to climb the mountain to get signals. It’s so hot he lefts the girls and Fifi go for a paddle in a little stream, which turns into a river of black evil smelling water, which sweeps them away. Hamish thinks they must have drowned. He is devastated. They climb higher and get lost on the Mountain.
Freeflyers find the girls, introduces them to the mythicals Pendragon and Kylin as Island creatures. They think they have zapped the girls off the Island on a plane to London to safety. But the energy of the island is stronger, and they end up back on the ditched aircraft. The water is rising fast and the plane is going to sink. They are probably going to drown.
Piers is captured, and dumped by a jealous Rebel in a gully on Devil’s Hole Island. The temperature is below freezing, and Piers was in wet clothes. He managed to get fires alight to dry out. He climbs out of the gully and sees something that looks like a village. He heads there, but is seen by another Rebel. This time it’s Nadia who likes him and wants to save him.
Polly and Lily go on a mystery fun flight. But Rebel Commander Rekrap arranges for them to be put on a Rebel plane with super star Brad Capriole. The plane is heading for Devils Hole Island for a meeting of the Rebels. The pilot tells the Commander the plane is going to crash, so a mid-air fight starts and the Rebels and the pilot parachutes out of the plane. The girls and Brad are left in the falling plane dropping to their death. Waiting for death the girls as it crashes to the ground they are amazed as the plane bounces, and they land safely. Unfortunately they are captured by a rebel and taken to the Dark Universe’s Village where a meeting is held to discuss finally capturing the Earth.
Eventually the fledging Freeflyers get together to rescue Piers. Miles followed by Polly got to the Rebels first, Miles was punching any Rebel that he could, while Polly had a few of them hopping around, rubbing kicked shins. Alison followed it up by whacking them on the head with her shoe. In amongst the shouts, screams and cries of pain, Lily and Lucy were biting every hand that came within biting distance, while Fifi was biting all the ankles that she could get to. Everyone was fighting, except Brad the film star who was hiding under the table. Mayhem rained till a couple of Rebels managed to break free to run and get help. The Freeflyers were soon overcome. Zack was more than angry, and told Miles, to save Piers from torture and death, he has to willingly give his mind to his twin Knox, who he had accidentally zapped. Miles agreed to save Piers. He was taken to the mortality room to his dying twin. He told his twin he loved him and started to cry. The tears fell on Knox. Had Miles saved Knox by becoming a vegetable or sacrificing his life?
