Action romance book series?

I’m looking for some action romance book series. Something with a found family aspect but each book is about a different couple. I love the security company, police, fbi, alpha males, mercenaries, contemporary romances, mystery, security company, tropes. I feel like I’ve basically read every series with these tropes. I need some more recommendations. No paranormal please! Can anyone recommend any good ones? Underrated ones are welcome but it has to be a series!
