Wolves of the South are series of stand-alone books, with a completed story arc and a happy ending for every couple.
Having said that, the adventure plot is at least as strong as the romance plot, so you're in for a fast-paced ride with the couple at the center. It's also best to read them in order (but not neccessary to understand the story), as some characters from earlier books will reappear in the later ones.
Also, please be aware that in this series, alphas are not good guys (I don't do debunked science) and my Wolves firmly close the door on any intimacy.
If you're happy with low spice and high stakes, I invite you to dive in!
