The Cowboy’s Marriage Mistake by Jessie Gussman

Rancher Cordell Stryker just wants to settle down on his ranch, and he’s convinced the twin sister of his best friend to tie the knot with him. But as the wedding day approaches, he finds himself drawn more to her sister. But that can’t be, because she’s his best friend.
