J.'s surprisingly funny and appealing texts, just as if she were Sienna. Because Gracie is fine. Always! She's had lots of practice being the sidekick, second best.

The letter waits in a book, in a box, in an attic, in an old house in Lambert, South Carolina. It's waiting for Candice Miller. When Candice finds the letter, she isn't sure she should read it.
