As readers of Book 1, SeaBEAN, know, after Alice discovered a mysterious black box on the beach called a C-Bean, which transported her and her five schoolmates from the newly re-inhabited remote island of St Kilda to New York, Melbourne, the Amazonian rainforest and the backstreets of Hong Kong on a series of daring adventures. Their hair-raising escapades and discoveries result in them saving their precious island. However, in the process the C-Bean has been damaged and is left apparently beyond repair. When the mysterious Karla turns up on St Kilda it seems she has the answer, but by resetting their mobile classroom the children, along with Spix their blue parrot and Spex their stray dog, are accidentally sent back in time. Before they know it, Alice and her new wartime companions are embroiled in even more dangerous exploits involving industrial espionage and nuclear hazards, as they journey through time to solve some dark secrets from St Kilda’s past and safeguard the future.
