Tripp’s Trivial Tie by Liz Isaacson

She needs a husband to keep her son. He's wanted to take their relationship to the next level, but she's always pushing him away. Will their trivial tie take them all the way to happily-ever-after? Ivory Osburn has a six-year-old son she hasn't told very many people about. Certainly not the handsome cowboy billionaire she's had her eye on for a few months. She starts a relationship with Tripp Walker, only to push him away when he gets too close. She's not sure how to explain things to him, and she's fine on her own. She is. Until she isn't. Until her ex threatens to take her son from her because she can't provide a stable income, a stable home, or a stable family life. Desperate, Ivory turns to the one person she doesn't want to think badly of her. Tripp's been trying to figure out how to get on the same page as Ivory for a while. When she comes asking him to tie the knot with her—on paper only, of course—he thinks maybe that marriage certificate will be the common ground they need. Plus, the sparks with Ivory are hot, and he wants to find out if they can have a real, lasting relationship. To keep her son, she'll risk her life. And anything else she has to—even Tripp's heart. Could their trivial tie be exactly what they both need to achieve a happily-ever-after?
