The Other Sister: An Agent John Adderley Novel

Mohlin and Nyström’s stellar sequel to 2021’s The Bucket List more than delivers on the first book’s promise. Former FBI agent John Adderley, the son of an American father and a Swedish mother, had lived in Sweden until he was 12; in the previous book, he moved there in 2019 after being wounded in a drug bust gone wrong. Under an alias “created by the Swedish authorities on behalf of the FBI’s witness protection program,” he’s become a respected member of the Karlstad CID. When John’s former partner from the FBI, Trevor, whom he thought dead, surfaces in Karlstad, he fears that he’s been betrayed and is being set up for assassination. John’s efforts to discover Trevor’s true motives in reconnecting coincide with his assignment to the high-profile murder of a tech executive who designed an innovative dating app. This nail-biter doesn’t let John off the hook for some hard choices he’s forced to make as the action builds to a jaw-dropping climax. Readers will be counting the days to see where these gifted writers take their lead next. Agent: Sara Tiala, Nordin Agency (Sweden). (Dec.)
