The mind is a dangerous place to hide…

Dr Eleanor Spencer is a well-respected psychologist with a seemingly perfect life. But when a series of women start to vanish, it dredges up memories of her sister’s unsolved disappearance and she finds herself drawn into the investigation.

Desperate, she turns to Lucas Hayne, a convicted serial murderer who revels in mind games. But when Lucas cryptically hints the answers lie buried in her past, Ellie’s carefully constructed world begins to splinter.

Because now she faces a terrifying possibility: the real monster might just be closer than she ever imagined.
