Book excerpt: TWELVE-YEAR-OLD GRACIE IS always flying under the radar of her overworked parents and outspoken siblings. But when she buys an old journal at a yard sale, Gracie is stunned to realize that everything she writes in the journal comes true—though sometimes in unexpected ways. At first Gracie uses the journal selfishly, controlling her mother’s BlackBerry and eliminating the dress code at school. But then she starts to think about bigger issues: what about world hunger? Global warming? World peace Unfortunately, before she can make headway on any of those issues, the journal falls into the wrong hands—and soon Gracie and her best friend/crush Dylan are rushing around town trying to undo the damage! This fun, warm, emotionally honest novel is both a fantastic adventure and a testament to the power of writing to change the world.
