Böcker i Spook Squad Trilogy-serien

Sam Ryan has no memory of her past. All she has is a crayon drawing of a woman with the word 'Mummy' scrawled underneath. For the ten years Sam's been with the State Police, she's used their resources to search for any clues to her identity. But it's as if all mention of her family has been deliberately wiped off the system, and no one knows why.Everything changes the night her missing partner, Jack, attempts to kill her. Charged with his murder, Sam finds herself accepting help from Gabriel Stern - a shapeshifter with secrets of his own. As Sam delves into her partner's death, she discovers that not only is he very much alive, but he's involved with an organisation that plans to destroy the human race. Worse, someone knows the truth about Sam's past, and it appears that they'd rather see her dead than have her uncover it.

Though neither event seems related, Agents Sam Ryan and Gabriel Stern quickly discover a link between the two - the military base known as Hopeworth. But are the serial killings a military cover-up that has gone dangerously wrong, or is there a deeper, more personal reason behind the murders of the red-headed adoptees? As the investigation continues, Sam discovers a connection between herself and the murder victims - a connection that implies a link to Hopeworth itself. With the killings escalating and the danger drawing closer to home, Sam not only has to battle to bring a killer to justice, but also has to save Gabriel's life. And the one person who seems to hold the key to what is going on, as well as what has happened in Sam's past, is the mysterious man who saved her life. But does she dare believe his words or the dreams she seems to share with him? Because this mystery man may not be just her enemy, but the enemy of humankind itself.
