She was a daughter, a wife, a mother. She was my friend. But what secrets did Eloise take to her grave? After her best friend Eloise dies from breast cancer, Cathy is devastated. But then Cathy begins to have disturbing dreams that imply Eloise's death was not all it seems. With a history of depression, Cathy is only just recovering from a nervous breakdown and her husband Chris, a psychiatrist, is acutely aware of his wife's mental frailty. When Cathy tells Chris of her suspicions about Eloise's death, as well as her ability to sense Eloise's spirit, Chris thinks she is losing her grip on reality once again. Stung by her husband's scepticism, Cathy decides to explore Eloise's mysterious past, putting herself in danger as she finds herself drawn ever deeper into her friend's great - and tragic - secret.
