"Sixteen-year-old Mafi Shahin knows life is not always fair. If it were she’d have just as much freedom as her older brother Rafi and her crush—basketball star Jalen Thomas—would see her as more than Rafi’s kid sister. And if life were fair, Mafi’s family in Afghanistan wouldn’t have to flee their homes to be safe. Life may not be fair, but as the Ghost, her high school’s secret avenger, Mafi vows to make it a bit more even, meting out karmic justice on behalf of classmates who’ve been wronged. They simply leave a revenge note detailing the transgression in the knot of the SOL tree, and Mafi takes care of the rest. But there are rules to being the Ghost: Don’t get caught. Never reveal your identity. Never involve the police, and definitely don’t get emotionally involved. But starting sophomore year, everything changes when instead of a revenge note, a wish turns up in the tree and Mafi breaks all her rules, putting her heart and even her family in Afghanistan at risk. Now Mafi will have to decide who she wants to be—the Ghost, making the world a just place from the shadows or something real, standing up for what’s right in the daylight." -- Publisher.
