I was hooked. It was fast and enjoyable. The storyline was great but i mostly just love the interactions between Knight and Moon, it's not only interesting but really comical.

I am a fan of Evanovich and always laugh my way through her Stephanie Plum books. This one made me laugh too, many times, and twice bringing me to tears I was laughing so hard. I almost dumped it after about 15 pages when I realized the characters were way out there (beyond Plum and Lulu) and the story line improbable. But I stayed with it because the interactions between Knight and Moon were funny, sometimes really funny. Plus you get the extra added attraction of two more really strange characters joining the 'team' and a four way dialogue that was even funnier. So if you want a ridiculous, fun read, this book will give it to you. Enjoy!

I loved it! It was exciting as well as educational...I'd never heard of lava tubes and then shortly after reading the book, I saw on the news that there is a lava tube here in Washington.

I have read everyone of her books and liked them all I am not sure what she was thinking with this book at all I had trouble getting thru it I wanted to put it down so many times but I kept reading because of who the author is.

I struggled to get through this book. Not her best work.

BORING BOOK! The characters are so flat. I can't believe Evanovich wrote this.
