Review: Twelve-year-old Macey, nicknamed Niner because of her missing thumb, thinks maybe she has bad genes, and that is why so many bad things happen to her. For example, she has had four mothers, and each one has left her. However, when Niner discovers a locket in her front yard, she thinks maybe it is a sign from her fourth mother. The quest to find her missing mother leads Niner and her friends into some dangerous situations. This book is packed with suspense and should appeal to a wide audience.
