Lindsey Nolan has it all: inventions paying large dividends, a dream job in the scientific village of Woods Hole, Massachusetts, and a stable of eager playmates. But when Lindsey wakes up in rehab with no memory of how she got there, her world is turned upside down. Her roommate, an HIV-positive teenage prostitute named Maggie, is the most volatile patient on the ward. The facility is plagued by disturbing thefts. And another theft unfolds when her competitor, an engineer named Karen Battersby, discovers and steals Lindsey’s astonishing new invention from her Woods Hole lab. Lindsey and Maggie must face the consequences of past transgressions if they hope to deal with present perils and ascend from the desolate world of the Bottom Dwellers.
