WHAT ROSE FORGOT

Barr takes a break from her bestselling series about National Park Ranger Anna Pigeon (Boar Island, 2016, etc.) for a one-of-a-kind stand-alone that follows the adventures of a woman committed to a Memory Care Unit for dementia as she fights to claw back her life.

There’s a lot of stuff Rose Dennis doesn’t know. She doesn’t know when and how she got out of Longwood or when and how she arrived there in the first place. She’s surprised and pained when people remind her that although she grew up in New Orleans, she moved to Charlotte, North Carolina, with Harley, her husband of 15 years, and that he’s died. At one point she’s not even sure whether she’s 68 years old or 103. After a pair of orderlies hustle her back to Longwood, however, Rose resolves that it’s the medications she’s being fed that are sapping her powers of mind and will and vows to stop taking them and escape again, this time for keeps. Fortunately, her second attempt takes her to the home of Melanie Dennis, Harley’s levelheaded, resourceful 13-year-old granddaughter, who’s more than ready to do whatever it takes to keep Gigi, as she calls Rose, two steps ahead of her pursuers. Unfortunately, one of those pursuers, a shadowy man armed with a knife, breaks into the old house where Rose is hiding out and tries to kill her. More adventures follow, some of them involving Rose’s hermitlike sister, Marion Bliss, who offers all the help a life spent online allows, some involving Karen Black, the hapless Longwood nurse Rose gets the better of on three separate occasions. It’s both a nuisance and a personal triumph when the media get hold of Rose’s story and label her “Gun Granny.”

A tour de force that thickens its thriller plot with a razor-sharp view of its heroine’s unreliable but perceptive mind.
