Ex-military dog trainer and a dog whisperer team up to heal Atlas, a grieving dog. David is a classic good guy - sexy, compassionate, 101% dog lover. Lyn shares the same kindness, and is strong in her way. There's some animosity at first, but their mutual dedication gives way to respect, and the admiration leads to growing feelings. Their bonding over Atlas is great, and leads to them opening up. 

I liked their romance, and how they constantly support and encourage each other. And Atlas is an absolute star! It was a joy to read his healing journey, his bravery, devotion, and all his cute moments. The suspense is good, and there was a lot of solid research into dogs in military. But the book had a slow start, and Lyn can be rather unreasonable at times. The culprit was not a surprise, but the ultimate revelation was.
