Orphaned computer expert Calista Cross is a graduate of the Deveraux College, the highly secret school for teenage spies. And at the moment, she's not coping. Ben Stanton's death has hit her hard and she's so unfocused that she's in danger of being mind-wiped and expelled by the Devereaux organisation. What Cally needs is some action, and a new case involving the suspicious deaths of several nanotech specialists seems just the thing. But an anonymous email hinting that Cally could be close to finding out about her parents turns the case from professional to very, very personal. And more than one surprise is waiting for her.
