Blue Mercy by Orna Ross

When Mercy Mulcahy was 40 years old, she was accused of killing her elderly and tyrannical father, Martin. Now at the end of her life, she has written a book about what really happened on the fateful night of Christmas Eve, 1989 -- and she desperately wants her daughter, Star, to read her explanation and finally understand. Set in Ireland and California, this compelling novel combines lyrical description with an enthralling, page-turning twists and surprises to create a heartbreakingly beautiful tale of love, loss and the ever-present possibility of redemption.
