"Fall," which now begins in late summer, has traditionally been the season when publishers bring out their heavy hitters. For Random House imprint Broadway, this fall's lead title is one of the most exciting they've ever published. It's by "one of America's most beloved television actresses" who "has had roles on (among other shows) 'Melrose Place' and 'According to Jim.'" Yes, we are talking about the debut novel of none other than Courtney Thorne-Smith, who, according to industry insiders, actually wrote the entire thing all by her own self. We don't yet have an advance reader's copy, so the book's description from Amazon will have to be what helps you determine where Thorne-Smith fits on the Paulina Porizkova-Ethan Hawke continuum.
