About five years ago, Brooklyn native Ilana Stanger-Ross (left) was working as a journalist up in Toronto and hosting the occasional mediabistro.com cocktail party. (We even have some photos kicking around the archives of her wearing the trademark boa.) These days, she's on the other side of Canada, finishing up her studies to pursue a new career as a midwife and celebrating the publication of her first novel, Sima's Undergarments for Women. Earlier this week, Overlook publisher Peter Mayer hosted a party for Stanger-Ross in his SoHo home; she returns to New York City this weekend for a Saturday afternoon reading at McNally Jackson and a Sunday night reading at Freebird Books in Red Hook.
