Anna is a typical high school student who is tired of writing boring research papers. When she decides to research angels, however, all that changes-in fact, her life changes. She learns that her grandmother and mother both know how to communicate with angels and that both have received signs from deceased loved ones. When she discovers her grandmothers angel cards, she uses them to communicate with her own angels.
After her presentation to her classmates, she reluctantly agrees to teach others how to use angel cards and is compared to a witch by the editor of the school paper. Anna faces the disapproval of her father, the vice-principal, and her best friend as her angels continue to leave her pennies as a sign of comfort.
When she is asked to assist a famous author in teaching teens about angels, Anna is not sure can handle the pressure.
