Whatever You Love — Louise Doughty

"I study the photo in the same way that a spy might study the face of a counterpart in a rival organization. I am calm as I make this promise: I am going to find out what you love, then whatever it is, I am going to track it down and I am going to take it away from you."

After the death of Laura's nine-year-old daughter, Betty, is ruled an accident in a hit-and-run, Laura decides to take revenge into her own hands, determined to track down the man responsible. All the while, her inner turmoil is reopening the old wounds of her passionate love affair with Betty's father, David, and his abandonment of the family for another woman.

Haunted by her past and driven to a breaking point by her thirst for retribution, Laura discovers the unforeseen lengths she is willing to go to for love and vengeance.
