The Marcelli Princess by Susan Mallery

Another continuation in the Marcelli Family. Mia Marcelli, the youngest sister, became a spy and gave it all up when the man she loved was killed. Going home and finding out she was pregnant was a shock. Five years later, her long "dead" love comes back to claim her and her son. But he isn't who she expected. She thought she fell in love with the "bad guy" but comes to learn she actually fell in love with a Crown Prince. He has come back into her life to steal her child.

Love this family! Love how they all stick together and support each other. As far as romances go, this one was pretty good. Didn't love the Rafael/Diego lead but I love all the other characters enough to make this enjoyable.
