So I feel very foolish to admit this, but I avoided this book for a few years because I thought it was a sequel. The problem was I never could find Bungalow 1. It turns out that there is no predecessor to this book. Bungalow 2 is named for the Bungalow that the main character of this story stays in while writing a Hollywood screenplay at the Beverly Hills Hotel - whoops! Maybe it would have been better for me if she'd stayed in Bungalow 7.
The storyline does indeed focus on a writer who is making the transition to Hollywood screenplays. She has always thought of herself as the average mom (who happens to have a successful writing career) living in Marin County. The opportunity to spend time in Hollywood is one she has to be convinced to do as it would take her away from her family for close to a year. (Though close enough still to visit on weekends when possible).
As you would expect with a Danielle Steel novel, you get to see some of the glitz and glamour of life. The story does take predictable turns that you can see coming as well. But you know it will and you just have to enjoy it for what it is.
