There’s a writer named Jenna Zark whose work I adore and who navigated through plenty of personal trials. While she was creating some of her early works of fiction, Jenna’s marriage to a Jewish cantor fell apart. And, she flailed about as she raised her young son, Josh. Her inspiring new book, “Crooked Lines,” chronicles her personal experiences and how they eventually led to smoother roads. Along the way she also explains how certain Jewish traditions and holidays have personal resonance.
