Thorns by Bella Scott

Luke LeBlanc, the son of a prominent senator, thought he had it all. But when Rose Mercer, the love of his life, left him just months before a walk down the aisle, he was shattered. He lost her after a disastrous night at a bar when he nearly destroyed his reputation and his family’s, and he convinced himself that he was better off without her.
When Rose shows up on his doorstep in the middle of the night four years later, however, he realizes he still aches for her. But Rose is carrying several secrets that have the potential to rock Luke’s world.
Will she be able to win his trust back, and his heart along with it?
