Intriguing at first and then just confusing and bizarre

I feel like I failed this book as a reader. I started this book hoping to read a story about a girl who was obsessed with a former high school friend who became wildly successful as an actress in Hollywood. Instead I found myself stuck in this bizarre story about a Scientology type philosophy. Personally I can't follow books where the storyline there's off in the direction that includes visualization and dream sequences and other nonsense. This book was marketed inaccurately, likely on purpose. The original storyline has marketed was something I definitely wanted to dive into, but unfortunately the story as written was something that barely held my attention the last 50% of the book. I did read the book to completion and was not satisfied or further enlightened by the ending. I found that none of the characters in this book has any redeeming qualities. I really did not care what happened to anyone in this book.
