They say everything happens for a reason. Or maybe it's Penny.
Penny Angelo is turning 10, and in the Angelo family, turning 10 is a very big deal. It's the day you become a junior guardian apprentice-the first step toward becoming a guardian angel. Not the robe-and-halo kind, but the real-life kind who help people in ways they'll never know.
Her first assignment? Helping Melanie, a bookish outcast who's being bullied at school. But as Penny navigates mean girls, not-so-great teachers, and a less-than-helpful mentor, she quickly learns that her mission is anything but simple. With wise advice from her scattered Gramps, her own determination, and a little magic, Penny discovers there might be more to Melanie's story than meets the eye, and along the way she finds her own guardian in a most unlikely form.
