Rival Forces (K-9 Rescue #4) by D.D. Ayres

When it comes to training K-9 patrol dogs, Yardley Summers always trusts her instincts. But when it comes to dating men, she keeps her heart on a very short leash. Mostly, she’s too busy with her four-legged trainees at Harmonie Kennels to commit to a relationship. Only two men have managed to distract her: a handsome Doctors Without Borders physician who’s suddenly gone missing—and the red-hot dog trainer from her past who’s suddenly back in her life…
Now a K-9 rescue team leader, Kye McGarren has never forgotten the days he trained at Yardley’s camp—or the nights he spent in her arms. When he hears that Yardley is on a mission to find the missing doctor, Kye is determined to keep her out of danger. With his K-9 partner by his side, he joins Yardley on a death-defying mission—one that reignites their mutual passion. Will Kye be able to rescue his romantic rival…without losing the woman he loves?

Review: I was given an ARC of Rival Forces from NetGalley for an honest review and this is my review.
I have really enjoyed this series by D.D Ayres and Rival Forces is another great K-9 book added to this series. I loved the chemistry between Yardley and Kye. I also found it interesting how they both had such polar opposite K-9's they were working with but they were such great matches for their handlers.
This book had a great romance but also an interesting mystery about what was going on with the guy Yardley was seeing and what happened to him and why did he just disappear that kept the reader interested throughout the book.
I am giving Rival Forces four out of five stars.
