Beautiful prose and intriguing characters can't quite save the confusing, and at times needlessly complicated, plot of this challenging psychological thriller, set on a fictional addition to the San Juan Island chain in Washington state, from Edgar-winner King. Talented, 52-year-old wood artist Rae Newborn suffers from severe depression, having survived several suicide attempts, as well as the death of her beloved second husband and their young daughter in a car crash. After being mugged by two strangers near her mainland home, Rae decides to wwork for healing by rebuilding the house called Folly that her great uncle, Desmond Newborn, constructed in the '20s as a way of mending his own war-wounded psyche. She capriciously dumps all her medications into Puget Sound, then lives in a tent while she digs and saws and chisels her way to bringing Folly and herself back to life. In uncovering and solving one murder, she works toward regaining sanity and--perhaps--love. While King skillfully portrays psychological illness, the book's sheer complexity of detail is overwhelming. There's more mass than the average mind can keep straight, and the passages about rebuilding Folly, especially, have a tendency to bog down. The denouement is a bit hokey, though definitely more attention-grabbing than all the rest put together. (Feb. 27) Forecast: Fans of King's Mary Russell and Kate Martinelli series will ensure strong initial sales, as will some serious ad/promo and a preview in each paperback copy of Night Work, currently on sale. This is far from King's best work, though, and may turn off some of her fans, leading to poor word of mouth and a weakening of sales down the road.
