S.J. Watson writes psychological thrillers about memory, identity and the danger of relying on information supplied by other people. Before I Go to Sleep follows Christine Lucas, who wakes each day unable to remember much of her adult life and secretly begins keeping a journal to compare what she is told with what she discovers for herself. The structure turns repeated routines and missing memory into the central suspense mechanism. Second Life follows a woman investigating her sister's murder through online relationships that draw her into deception and risk. Watson's novels are tightly focused, contemporary and twist-driven, with unreliable perception more important than police procedure. They fit psychological thriller, domestic suspense and memory-based mystery. Read more Less
