"London, 1968. The world is changing again, and forty-one-year-old John Willcox has no interest whatsoever in watching it. But when an Ottoman Turkish translation of a Portuguese botanical work is linked to four missing nuclear submarines—before turning up in his flat—he has no choice but to join in the spectacle. Blackmailed into connecting the dots between the sixteenth-century manuscript and the twentieth-century subs, he’s thrown together with a motley crew of family and friends he’d vowed never to see again."
