In Missing Dad: Ransom (Book 6 in the series), an escaped criminal from Joe's father's past threatens his life – and Joe and his mates take the fight to the enemy. So they steal a consignment of cocaine from under the noses of the smugglers by swimming beneath the hull of the ship where it is attached; sending it swimming straight into the arms of Marseille customs officials. And escaping alive – just!
In Antibes, a heroin-manufacturing bunker is busted, thanks to the hacking skills of Joe's half-Italian cousin Tommaso. Then Tommaso goes one better and hacks the Kremlin. Which leads to the daring hijack of a remote-controlled Russian ship carrying an illegal cargo of deadly hypersonic Zircon cruise missiles. The youngsters nearly pay for this with their lives in the freezing waters of the North Atlantic.
Meanwhile Joe's father, impatient to deal with his pursuers, leaves a place of safety and is captured by the deadly Italian Camorra. The chilling deal they want is – Tommaso, who grew up with the Camorra, returns to them to take up active service again. His hacking skills are what they want in order to plunder container ships coming into the ports of Naples and Marseille. But Tommaso turns the tables by hacking the Camorra's links to a Colombian drug baron. And when this deadly game involves hijacking the drug baron's nuclear submarine packed with 200 tonnes of cocaine and spiriting it away from South America via the Arctic Circle, it's all to play for.
