This is the first book in The Five Packs series. This book was about Killian the alpha of Una’s pack. Una was a last bloomer. She is in her later 20’s and still hasn’t gone through her first heat. She was attacked as a child and has a permanent injury. She is the lowest ranked pack member. One day she finally goes through her heat and learns that Killian is her mate. He originally rejects her as his mate. Killian’s wolf instantly wants her as a mate unlike the man. As time goes on Killian and his wolf start becoming one with their thoughts and feelings. Even though Una is a week wolf she doesn’t just roll over allow anyone to walk over her. When Killian finally comes around and wants to be her mate she makes him work for it. I can’t wait to see who the next book will be about. Paulina Lear and Liam Sanderson did a great job narrating this book.
