It Was Always You [EPUB ebook] 

She never realized until she lost him that he was the only man she’d ever love.
Katy and Steven were the loves of each other’s lives until a tragedy and the fallout of Steven’s injuries drove the couple apart.
They share a son, but Katy and Steven have moved on with their lives, dating other people, and neither has seen the other in five long years. But when Steven comes knocking on Katy’s parents’ door after learning she’s back in town, Katy is forced to face her estranged husband and the love that broke her heart, and his intentions regarding their all-but-over marriage are soon made very clear.
The only problem is that as simple as it would be for them to walk away, seeing just what it means to move on and start a new life may not be as easy as they once thought.
