Jack Courtney has lived in the UK 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 poachers. The three friends will need their wits about them if they are not only to save Jack's parents, but their own lives too.

Second in a brand new action adventure series starring 14-year-old Jack Courtney - a hero to rival Alex Rider - from worldwide bestselling author Wilbur Smith. Jack and his friends Amelia and Xander are in Zanzibar diving for lost treasure to support Jack's mother's coral protection project. Going further than usual on their last day, their dive boat is lured into a trap and captured by Somali pirates. Determined that his mother shouldn't pay a ransom for their release, Jack won't give up his attempts to escape. Transferred to a militia training camp for boy soldiers, the trio's only hope is the resourceful Somali boy Mo who befriends them. Can they outwit the ruthless General Sir and his merciless troops in the second gripping adventure from the authors of Cloudburst?

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?
