This book is written by Carolyn Keene. It is one of the newer Nancy Drew books and is the last book of the Malibu Mayhem trilogy. This book is good. The trilogy is about when Nancy and her friends go too California in a house by the beach and a lot of weird things start happening. The original ones are a lot better than the new ones. It's a bit predictable and easy too guess what will happen. The characters are not very good and don't seem real. I think the age groups that would like this book are 8-11. The ending wasn't good and they didn't have the mystery completely solved until the last couple of pages and I didn't like that.
