The Black Coats by Colleen Oakes
For months, Thea has lived in a fog of grief and anger. Not only was Natalie, her cousin and best friend, murdered, her killer is walking free. Then one day a black envelope appears on her desk. Following its instructions, she finds her way to the Black Coats, a secret society of women working to provide justice for girls and women who have been harmed and to make the world a safer place for them. Finally Thea feels like she has a purpose in life. She even starts dating Drew, a boy who is not only good looking, but kind and considerate. But not everyone in the Black Coats has the same agenda, and soon Thea must decide where the line between justice and vengeance lies, and on which side of it she is willing to stand.
Full of action, sisterhood, and romance, this book will pull you in and keep you turning pages to the very end. Recommended for readers in high school and up.
