The start of a Brand new Wilbur Smith series for readers of 11+ - starring fourteen-year-old Jack Courtney.

Jack Courtney has lived in London his whole life. But this summer his parents are travelling to the Democratic Republic of the Congo for a gorilla conference, and they've promised to take Jack and his friends with them. When his parents go missing in the rainforest, abducted by mercenaries, nobody seems to have any answers. Jack is pretty sure that it's got something to do with the nearby tantalum mines, but he needs to prove it. Along with Amelia and Xander, Jack must brave the jungle to save his parents. Standing in his way is a member of his own family - Caleb Courtney.

There are western gorillas, forest elephants and hippos. But there are also bandits, mercenaries and hostile tribes. The three friends will need their wits about them if they are not only to save Jack's parents, but their own lives too.

Third high-octane instalment in the bestselling author's compelling Jack Courtney Adventures for readers 10+, following CLOUDBURST and THUNDERBOLT.

On the pretext of making a film for his mother's environmental protection work, Jack wangles an expedition to the Arctic with his friends Amelia and Xander and cousin Caleb. But Xander's investigations into the mysterious backers funding their adventure raises Jack's suspicions. Is the renewable energy investment company really as environmentally responsible as it claims to be?

While sledding with dogs, ice fishing, driving snowmobiles and sleeping in a self-made igloo, accidents beset them. Then disaster strikes when Caleb takes on a pack of wolves.

Can Jack really trust his mother's friend Jonny Armfield to come to their help, or is he part of the problem?
