Adrian and Andy did not like the idea of a new mother. Their mom had passed away two years ago. Jill and Carol aren't too sure they're going to like it either. Mr.Dallas (Adrian and Andy's dad ) got married to Emily(Carol and Jill's mom). The house on the hill above them is a beautiful old mansion with two mysterious old ladies living in it. Jill feels a mystery floating about and wants to solve it. I was so excited to read this book because it's set in San Francisco and we're going to San Francisco next month!If you enjoy mysteries and exciting books then you will love this book. My mom also reviewed this one. You can check it out here.
