1964. Houston, Texas. Evie Barnes and all her friends are the sort who wear bold makeup, laugh too loud, and run around with boys. Most of all, they protect their own against the world. They're the bad girls. When Evie is saved from a sinister encounter by a good girl from the "right" side of the tracks, every rule she has always lived by is called into question. Now she must redefine what it means to be a bad girl-- and rethink everything she knew about loyalty.
