This is my first book by Ayres. It also happens to be book six in A K-9 Rescue Series. This s the story of Macayla “Mac” who’s a pet detective and Oliver a K-9 Search and Rescue operative. The teasing banter, sexy flirting and comedy between the two were what made the book so good. After finishing Physical Forces, I had to go back and pick up the other books just to see what I missed. I am happy to say I have found a new one click author. I cannot wait to read my next one.
