When an FBI agent goes missing while hunting a serial killer, she’s declared dead in absentia — that is, legally presumed dead, even though there’s no body. But then she’s found alive six years later, with no memory of her time away, and struggles to step back into her old life. Her husband remarried and is raising her son with a new woman. And, while attempting to help her old colleagues with her case, she discovers she’s the chief suspect in a new crime.
