When thirteen-year-old Samantha moves to a new town, she decides to reinvent herself. She wants to be called SJ now. She's going to be cool and mysterious. But above all, she's going to pretend to be healthy.

SJ suffers from chronic eczema and allergies - she's sick of doctors' appointments and tests, sick of itchiness and pain, sick of looking different, feeling different. All SJ wants is to be 'normal'. She'll do whatever it takes to keep her illness a secret. After all, would new friend Livvy or cute boy Sam still want to hang out with her if they knew the truth?
