This Changes Everything (McLaughlin Brothers #1)
Jennifer Ashley

Now he’s back in my life, the two of us reconnecting when my best friend marries his brother. I haven’t seen Zach for years, now he’s next to me, irresistible in his tux. He looks at me with his sweet blue eyes, and his mouth quirks just a little. Enough to show me he’s noticing me, and wondering how we’ll get through this.
I’ll try to keep it casual, but I know inside that seeing Zach after all these years ... is going to change everything.
The McLaughlin Brothers are light, fun, humorous, short, feel-good romances. Meet the four McLaughlins: Ryan, Zach, Ben, and Austin, who will do anything for each other, and their spirited heroines: Calandra, Abby, Erin, and Brooke
