Blood Wounds is all about Willa, the ugly-stepsister type to two princess types. Willa's stepsisters are privileged, poised, and experienced - everything that Willa's not - but they've always considered each other family and gotten along really well. They live harmoniously with Willa's mom and stepfather (the girls' dad) in a nice house, and Willa only gets slightly annoyed that the girls get their every desire from their mother.
However, the idea of this "happy family" comes into question the second Willa starts receiving strange phone calls about a man named Budge. It turns out that "Budge" is Willa's biological father, and that he's wanted for the murder of his wife and three daughters - sisters Willa didn't even know she had. Hearing of her father's new family and difficulties sparks feelings in Willa that she didn't know she had, and leads her to question everything she's known up until this point.
I loved Willa's character, and I loved the way Pfeffer explored the idea of family and the dynamics of blended families. It was interesting to read the "sisters'" different perceptions of each other and of the way things were in their family.
