In New York Times bestselling author Nevada Barr's gripping novel What Rose Forgot, a young grandmother wakes up to find she's trapped in her worst nightmare.

WHAT SHE FORGOT IS FRIGHTENING.

Rose Dennis wakes up in a hospital gown, her brain in a fog. With no memory of how she ended up at this unknown medical facility, Rose is sure that 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 stop taking her medication. Becoming more and more lucid, she devises a plan of escape.

WHAT SHE REMEMBERS IS DEADLY.

The only problem for Rose now is: how does she convince anyone that what she's experienced is true? With her memory shaky, how can she even trust herself? Enlisting the help of her computer-hacker sister and her teenage granddaughter, Rose begins to piece together fragments of her life. But any lingering doubt that she's in real danger is erased when a stranger starts showing up at her now-abandoned house, determined to get rid of Rose once and for all.
