Born into a famous family of exceptionally talented people, fifteen-year-old Claire Walker has deliberately chosen to live an average life. But everything changes the night of the Spring Fling, when her parents decide it's high time she transferred to Cambial Academy--the prestigious boarding school that her great-grandfather founded for students with supernatural abilities.

Despite her attempts to blend in, Claire stands out at Cambial simply because she is normal. But unbeknownst to her new friends, she has a powerful gift she considers too lame to admit. Suddenly, the most talented students in school--the Exceptinals--begin to disappear. In an attempt to find out what happened to them, Claire comes across a prophecy foretelling a mysterious girl who will use her ability to save Cambial students from a dire fate. Could she be that girl? Claire decides there is only one way to find out: she must embrace her ability once and for all.
