This is the first book in the Guardians Unleashed Series, but I have to say I was hooked to the series from the Prequel Rising Danger, which introduced me to the Phoenix K-9 Security and Protection Agency, an amazing team of courageous women compromised, with the help of their talented canines, to protect and secure their people from different harms. You don’t have to read the Prequel because this book stands alone perfectly, but I loved that I already knew a bit of this tightly bonded team.This book is Cora Isaksson’s story. She thinks she is the least brave of the team, but the story will prove her wrong. She struggles with guilt over her brother’s drug addiction ever since he left home angry and resented. What she never expects is for Bradley to return, and to be thrown, along with her narcotics detection expert K-9 Jana, into a battle against the same drug cartel he belonged to and wants him back.DEA Special Agent Kent Thomson has a personal reason to bring justice to this particular cartel and has been tailing them for some time without success. But he feels he is very near to discovering them. But when the DEA office asks the Phoenix Agency for Cora to help Kent in his mission to capture the drug cartel leaders, Kent thinks Cora and her dog will only tamper his job. But when he gets to know her, he realizes they might be a good asset in helping him delivering justice. But is he the one to deliver justice? Or does he need to turn to God for help?As Cora becomes a target and the mission becomes highly dangerous, they both have to make a good team if they want to succeed, alive… And as the story develops, Kent’s protective nature over Cora turns into something so much deeper as he fears he might lose her in this mission. And not even just her, more lives hang in the balance as they battle this evil, trusting that God is Bigger and will help them bring them down without losing their lives and ultimately their chance for a future together.I loved this book! It’s filled with everything I love: a page turner plot with unexpected twists, lots of intrigue, danger, adventure, family theme, sweet romance and an inspirational message! The romance was swoon worthy! And I liked that Cora and Kent were relatable characters, flawed, yet inspiring. I loved how Kent’s aloofness toward Cora changes into protection, admiration and finally love! Also, his character growth was humbling. Cora had a huge heart, a quiet strength, and courage to do what it’s right even if it kills her (literally too), it pained me how she suffered and felt guilty because of her brother addiction. Having a loved one in this same situation, this book was so insightful for me to understand better the struggles they face and to remind me how God loves each and every one of us in spite of our flaws and brokenness and is always willing to forgive us and give us the grace we need to start over. He never grows tired of us! And He can always bring good out of the bad and pain, if we trust in Him. This is definitely a book I recommend! You won’t be able to put it down, and you’ll fall in love with the Phoenix K-9 Team members (K-9 included). Love the friendship they share and how they have each other’s backs. I can’t wait for the next story in this series!!I received a complimentary story from the author but wasn’t required to post a positive review. This is my honest and unbiased opinion.
