As if a terrifying nightmare wasn't bad enough, being woken from it with the news that she'd been strangled in a parking lot didn't make for a great start to the day for FBI Agent Ellie Conway.

Extraordinary and bizarre packages delivered to her home, a sniper aiming for her – twice in one day – and a vehicle that looks like Swiss cheese, tends to make a girl lose her sense of humour.

More mistaken-identity deaths, bank robberies, a hospital murderer, an unexpected cold case, and a rendition to a black site, conspire to demand more than the usual amount of kickass determination required of SSA Conway.

Ghosts from the past, forcing themselves into her present life, with vengeance on their minds, threaten Conway and the lives of others, reminding her of the fragility of memory.
