Close, a novel of family and suspense. Single mom Kik Marcheson is doing the best she can - but effort doesn't seem to count for much in the parenting department. Her oldest daughter is swimming in the deep end of adolescence; the middle-child slash good-girl is fraying along the edges; and the baby, a quirky kindergartner, has befriended an imaginary playmate. When a TV therapist offers help, they take it. And then things go from bad to terrifying.
