Abby Stern is very much looking forward to leading a biking trip from NYC to Niagara Falls – until her mom, an old one-night-stand, and some uneasy memories are added to the mix. In Jennifer Weiner's new novel, The Breakaway, that two-week trip becomes filled with tension: sexual, political, and familial. Weiner tells NPR's Juana Summers how different women manage their mothers' expectations, and how she learned to see "almond moms" quite differently while writing this novel.
