A Not Too Surprise Ending

An interesting and compelling kidnapping investigation with a twist ending. About halfway through I was wondering why Olivia and Brock didn’t see the writing on the wall. Good read.

An absolute must read book and series!

Olivia and Brock have had many unusual and outright crazy cases throughout their careers, but I have to say that this one has to be at the top of that list! Lol! For both of the very experienced Agents, it certainly takes a lot to shake them up or surprise them, but their current case does just that and more. It's a fabulous story by this incredibly talented author duo!
I would definitely recommend this book, series, and exceptional authors.

I truly can't wait for the next book in this series! I swear, Olivia will never want to go on or agree to a "vacation" again! Lol!!!🤣😂

Another well written Book

I love reading books from this author. They always keep me on my toes and the endings are always unexpected can the next one come out like tomorrow please please please?

Interesting story line, parents should know that they need to trust their kids. What is with the court system, seems like they feel untouchable. Abuse of his powers with his family and the church.

Sure hope Vegas treats them well, but we know that isn't gonna happen.

This was an awesome story about Olivia and Brock looking into a kidnapped girl and who is responsible but there there is many twists and an ending you didn’t see coming involving the seven sins of somebody. Thank you for this great story with suspense and drama.

An unbelievable storyline

Elle has done it again! I thought I had it figured out but the twist at the end left me in awe. How she knows so much I'd beyond me! The ins and outs of writing
eludes me.

Deadly Sins

What a great book! The authors outdid themselves. The seven deadly sins still stand the test of time. I highly recommend reading this book.
