After suffering a savage assault in a bathroom as a girl, Gertie meets the man of her dreams. Her trauma soon vanishes as they begin to build a life together. However, with the sudden death of her beloved Jack, and the return of her school bully—Bea—years later, Gertie's long-buried trauma bubbles to the surface. All the think is one thing: Revenge.

Inserting herself into Bea's life, nobody is safe—not her parents, not her children. Hell, not even the pTA members of her daughter's high school. Starting a sordid romance with Bea in a bid to destroy her life from the inside out, Gertie soon learns revenge is messier than she thought.

BUT A GIRLS' GOTTA DO WHAT A GIRL'S GOTTA DO.
