Corporate wife-turned-author Danielle Rollins wrote a guide to hosting parties during a time when her own life was in shambles behind the scenes. Rollins managed to craft “Soiree: Entertaining With Style”while her teenage daughter Carlyle was recovering in the hospital after a serious car accident, and during Rollins’ own messy divorce from her husband, Glen, an heir to the Orkin pest-control business. “My middle child was badly injured in an accident and ultimately spent several years recovering,” Rollins writes in the book. “I had forgotten how great a party could make me feel.” Carlyle, who endured 100 surgeries, is photographed in the guide to entertaining, along with elegant tea parties, dinners and New Year’s Eve bashes. Rollins, a contributor to Veranda magazine, celebrated the tome’s release at Saks Fifth Avenue last week with her friends Lela Rose, Celerie Kemble, Jill Fairchild, Hilary Dick and Christopher Burch. The book is published by Rizzoli.
