Gracie has never felt like this before. One day, she suddenly can t breathe, can t walk, can t anything and the reason is standing right there in front of her, all tall and weirdly good-looking: A.J. But it turns out A.J. likes not Gracie but Gracie s beautiful best friend, Sienna. Obviously Gracie is happy for Sienna. Super happy! She helps Sienna compose the best texts, responding to A.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.
