Avenging Angel (The Blood Debts trilogy)

From the day she was born, Esme was branded a curse. Her violent father convinced everyone that she had brought nothing but misery to their lives. All because she was not the son he'd longed for. Feared and shunned by those around her, Esme finds comfort only in the love of her mother—the one person willing to stand between her and a man consumed by drink, rage and cruelty.
When a brutal outburst leaves her mother dead, Esme's world is torn apart. Sent to a children's home while her father awaits justice, she refuses to stay. Alone and terrified, she runs away with another girl, unaware that her mothers parents are desperately searching for the granddaughter they have never stopped loving.
Eventually starting a new life with Bridget and John Lee, things seem to pick up, but when her mothers brothers, Frankie and Jimmy, go for retribution, the two families go to war.
For Esme the scars of her childhood run deep, and some wounds never heal. As she learns to live with what happened, the lies that shaped her life begin to unravel, exposing the family who stood by while her mother suffered. The frightened little girl they abandoned is gone. Now, only one thing remains. To make them answer for their sins. A gripping saga of survival, betrayal and a young woman's relentless quest to make the monsters pay, and pay they will, in blood.
