Nightbitch : a novel
(Book)

An ambitious mother puts her art career on hold to stay at home with her newborn son, but the experience does not match her imagination. Two years later she steps into the bathroom for a break from her toddler's demands, only to discover a dense patch of hair on the back of her neck; her canines look sharper than she remembers. Her husband dismisses her fears from faraway hotel rooms. She struggles to keep her alter-canine-identity secret, and discovers the mysterious academic tome which becomes her bible, A Field Guide to Magical Women: A Mythical Ethnography. A group of mothers involved in a multilevel-marketing scheme may also be more than what they seem. -- adapted form jacket
