Welcome to the website of the Adventure Island series by Helen Moss. 

Thank you for dropping by.

If you enjoy following Scott, Jack, Emily and Drift as they solve ever more baffling mysteries on the island of Castle Key this is the place to be! Have a look around and join in the fun.

Click on the links below to find out about the books, the author and illustrator, the stories and settings. You can read blog posts from the four intrepid super-sleuths, explore the island and keep up to date with the latest Adventure Island events and competitions. You can even join the Special Investigation Team (S.I.T.) to find hidden pages of games and puzzles.

We love to hear from you too, so why not send in a question for the author, a picture for the art exhibition in Dotty's Tea Rooms, a picture of your pet for Drift's Canine Division of the S.I.T. or a recipe for Aunt Kate's collection. Or just tell us about any mysteries you've solved lately or share your favourite pizza topping brainwaves with Jack.

NEWSFLASH:You may have noticed that Helen Moss has been spending rather a lot of time with her other team of young mystery-solvers lately. Cleo McNeil and Ryan Flint of the Secrets of the Tombs series have a new adventure - The Serpent King - coming out next week.  You could win a set of all three Secrets of the Tombs books. Find out how here . . . 

NEWSFLASH: Drift has a new recruit for the Canine Division. Welcome to Sammy. To find out more, enter the Special Investigations Team area . . .
