I think I am addicted to this series! I absolutely love each story and, once I start reading, I can’t put them down until I’m finished. Then, I’m disappointed that I have to wait for the next release. The books don’t end on cliffhangers but they are SO GOOD that I don’t want to wait to start reading the next one! Each one is as good as the others. I haven’t been disappointed in any of them. (These are Christian/LDS so there is definitely an element of faith/religion in them.) They have no swearing or sex but there is violence, torture, killing, etc. I find them riveting and realistic. The pacing is fast and they are easy to read. I highly recommend all the books in the series and I look forward to reading more as the author publishes them. I hope 🤞🏻 it’s soon!

Traitors and truths

An exciting action packed book about the difficult life of a spy. It's all here, the violence, mind games, cunning, planning, coping techniques, and adrenaline producing uncertainties. I read this book without any break as I was completely captivated by the author's words!

The characters came to life through the writing, keeping me completely immersed in story. Each book in this series is stronger than the last. Be sure to read the books in order to appreciate them to their fullest. Incredible series that leaves you wanting more!

Warning: 5 Star binge reading book!

Loved the pacing, the story arc and wow! The UTAP team with Kate and John are flawed lovable characters while the antagonists are deplorable and despicable to the max! Spy tech and tricks of the trade revealed are super cool. Don’t know how Amy Martinsen outdid herself but yep, this book is better than 1 & 2, can’t wait to read book 4. Be warned, once you start, it’s nearly impossible to put it down!

Amazing, and intense

As a former police officer, this book hit differently. I have read the series in order and never felt so much as I did in this book. And lots of tears. Ms Martinsen is a talented author and paints mental pictures. She can weave heart and soul into a situation so harsh and cruel, it seems impossible to have the opposites so interwoven. I greatly enjoy the clean stories and language.

I started reading this series so I had a book that I read that was up for a Swoony award. Unfortunately, this one did not make it to the second round but I am now addicted to it to the Untapped Source series!! I read all 3 books in the past week and now have to wait for number 4! I love the relationship with John and Kate and hope we get more intel on Kate's father in the next one.

A lot of action for the main character in this book. I didn’t realize there would be another one in the series, so it was a fun surprise.
