A 16-year-old international assassin yearning for a "normal" adolescence fakes her own death and enrolls as a senior in a suburban high school. She quickly learns that being popular can be more painful than getting water-boarded.
Based on the true story of an award-winning investigative journalist -- and avowed atheist -- who applies his well-honed journalistic and legal skills to disprove the newfound Christian faith of his wife... with unexpected, life-altering results.
Echo must deal with the regular dramas of high school, in addition to grappling with the murder of her older sister, Zoë. But when Echo receives a diary from Zoë's boyfriend, she begins to untangle the secret life her sister lived.
