Dee Henderson is indeed the Queen, but she hasn't written anything new in what, 4-5 years. It grieves me, but she must be having Life Intrusions.
You might like the Steeple Hill LI Suspense books. I particularly recommend Kathryn Springer, who writes a very well crafted rom suspense. Outside of that line I've liked Kathy Herman and Kristin Heitzman.
If you want a deeply felt story in the romantic/family saga line, pick up almost anything by Lisa Wingate. Her prose is very powerful and moving, and the romances absolutely ring true.
You've got a wealth of bookseeking to do. Happy reading!
