Joe and Molly in the Seychelles

Joe and his little sister Molly come from a very poor but happy family.
Their lives change suddenly when their father announces he has won 1st prize in a raffle. It's a family trip to the enchanting islands of the Seychelles, staying on a luxury sailing ship!
Whilst Joe and Molly are sitting together on the deck looking up at the stars, Joe smells smoke. He turns around to see huge flames. The beautiful sailing ship is on fire!
Joe and Molly jump into a little wooden boat perched on the side of the sailing ship and Joe rows frantically away from the blaze towards the safety of the other islands and now their adventure begins!
They discover little islands where they swim underwater amongst a kaleidoscope of fish, look up in wonder at beautiful birds, sample the delights of exotic fruit, meet local fishermen and walk alongside giant tortoises. They feel they're in paradise!
What is going to happen to Joe and Molly? Will they be reunited with their parents?
