This book is about the scarred Guardsmen, Kellan. The backstory behind his scars was revealed, and it turns out Kellan was scarred both externally and internally. Kellan received his scars from an attack on a poor village, while he was trying to save the lives of three little girls. And thanks in part to the malice of one truly evil villain. Kellan was deeply impacted by those he couldn't save and blamed himself. Once his brethren tracked the man responsible they have been on the case ever since. His mate and Dove shifter, Olive has something to say about Kellan's scars and wants to help her mate finally heal from those old wounds. But to do so, the gang have to settle the score with the man responsible for Kellan's scars.There is another merging mating forming in this book, I think it got started in the previous book, but its mentioned a bit in this one. Olive has to break Kellan's defenses to get him to allow her in and allow her close. They have a mild courtship when compared to the other couples,except that one incident. Bring on the next one.
