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.
