The miscreants

"When their mother throws herself off the balcony of their Islington council flat, brothers Harry and Ethan are set adrift. Years later, Harry moves to Canada to escape friendships and drug deals that have gone sour, and Ethan enrols in university, hoping to find answers to life's biggest questions. But when Ethan goes missing, Harry comes home. He traces Ethan to Sweden, and to Gretta. Gretta holds the clues to Ethan's mysterious connection to a doomsday cult, but will Harry find him before it's too late?"--Provided by publisher.
