Rachel Renee Russell is a lawyer who prefers writing children's books to legal briefs (mainly because books are a lot more fun and pyjamas and bunny slippers aren't allowed in court). She has raised two daughters and lived to tell about it. Rachel lives in northern Virginia with a spoiled pet Yorkie who terrorises her daily by climing on top of her computer and pelting her with stuffed animals while she writes. And, yes, Rachel considers herself a total Dork.
