I've Got Your Number| Sophie Kinsella; The Dial Press; 448 pp.; $26; fictionFans of Sophie Kinsella's amusing Shopaholic novels won't want to miss her latest foray into chick lit.

After she loses her emerald engagement ring and has her cellphone stolen, Poppy stumbles upon another phone in the trash that belonged to the former assistant of Sam Roxton, a handsome exec at a consulting firm.Complications (and humor) ensue as Poppy convinces Sam to allow her to keep the phone until she finds her ring — promising to forward his messages, Poppy-style.USA TODAY says *** out of four. "Delivers all the usual Kinsella hallmarks — sharp insight into the current state of relationships crossed with laugh-out-loud screwball situations — but with a digital-age twist."That Woman: The Life of Wallis Simpson, Duchess of Windsor| Anne Sebba; St. Martin's Press; 283 pp.; $27.99; non-fictionWallis Simpson — the American for whom Britain's king famously abdicated — is everywhere these days.
