My Forever, My Angel (Ryan Family #1)
Loni Ree

Lukas fights his grandfather’s request that he marry an ally to secure the business partnership. When plans change, he offers one of his brothers in his place. After he realizes the woman being offered is his “Angel,” Lukas refuses to watch one of his brothers marry her, so he decides to marry Madison Steele himself. Once they are married, Lukas must fight to gain his wife’s love while trying to protect his company from someone intent on destroying it.
This is the first book in the series that follows the Merger of the Ryan and Steele Families. Each book is a standalone book but the stories are intertwined and are best if read in order.
