Two years after finally being reunited, Abigail Thomson and Gideon Hawk are happily married and living in Cornwall with their children. While Gideon is busy focusing his energies on his musical career, Abi makes an unexpected discovery of old diaries dating from 1950. As she and her daughter read through them, the reasons behind Abi's mother's destructive actions become much clearer, and they discover a shocking sixty-year-old deception. Meanwhile, Simon Dean, the vengeful ex-drummer of Gideon's band NightHawk, is about to make life very difficult for them all—again—and he is prepared to go to desperate lengths to achieve his goals.
