Sixteen-year-old Flannery Malone has it bad. She's been in love with Tyrone O'Rourke since the days she still believed in Santa Claus. But Tyrone has grown from a dorky kid into an outlaw graffiti artist, the rebel-with-a-cause of Flannery's dreams, literally too cool for school. Which is a problem, since he and Flannery are partners for the entrepreneurship class that she needs to graduate. And Tyrone's vanishing act may have darker causes than she realizes. [...] When Flannery decides to make a love potion for her entrepreneurship project, rumors that it actually works go viral, and she suddenly has a hot commodity on her hands. But a series of shattering events makes her realize that real-life love is far more potent — and potentially damaging — than any fairy-tale prescription.
