Don’t Believe a Word, by Patricia McDonald

Characters:
Eden Radley, an editor for a publishing house in New York City, whose Mother Tara, has committed suicide after murdering her son, Eden’s half-brother Jeremy, who has an incurable disease.
Flynn Darby, the father of Jeremy and husband of Tara, and an author
Hugh Radley, Eden’s father

Eden Radley does not have a good relationship with her mother, Tara. Eden has never forgiven Tara for abandoning her and her father and marrying her ‘soulmate’, Flynn Darby when Eden is still a young girl. After her new marriage Tara has a child, a buy named Jeremy who sadly is afflicted with a fatal disease. The family moves to Cleveland so that Jeremy can receive treatment from a renowned doctor there. But Eden receives the news that her mother has killed her son and taken her own life at the family’s home, while the father was out of town. Eden takes time off from her job as an editor at a publishing house in New York City and goes to Cleveland for the funeral. What she finds there is anything but a clear case of murder/suicide.
This book kept me guessing the whole time. Was it the father/husband or even Eden’s father? Was it a jealous lover? While the plot did some stretching of what I would think was entirely possible, if you’re willing to go along with that, it was very intriguing. Lots of suspects in a story about a girl who wants to find the truth and also come to terms with her sad relationship with her mother. Finding out what happened becomes a way for Eden to make up for her coldness towards Tara and the brother she refused to acknowledge while he was alive.
