In New York Times best-selling author Nevada Barr's gripping stand-alone, a grandmother in her 60s emerges from a mental fog to find she's trapped in her worst nightmare.

Rose Dennis wakes up in a hospital gown, her brain in a fog, only to discover that she's been committed to an Alzheimer's unit in a nursing home. With no memory of how she ended up in this position, Rose is sure something is very wrong. When she overhears one of the administrators saying about her that she's "not making it through the week", Rose is convinced that if she's to survive, she has to get out of the nursing home. She avoids taking her medication, putting on a show for the aides, then stages her escape.

The only problem is - how does she convince anyone that she's not actually demented? Her relatives were the ones to commit her, all the legal papers were drawn up, the authorities are on the side of the nursing home, and even she isn't sure she sounds completely sane. But any lingering doubt Rose herself might have had is erased when a would-be killer shows up in her house in the middle of the night. Now, Rose knows someone is determined to get rid of her.

With the help of her computer hacker/recluse sister, Marion, 13-year-old granddaughter Mel, and Mel's friend Royal, Rose begins to gather her strength and fight back - to find out who is after her and take back control of her own life. But someone out there is still determined to kill Rose, and they're holding all the cards.
