Boyfriend By Mistake by Elana Johnson

She owns Heartwood Inn. He needs the land the inn sits on to impress his boss. Neither one of them will give an inch. But will they give each other their hearts?
Alissa Heartwood captains a fishing boat and is the pastry chef for her family owned and operated empire on the island of Carter’s Cove. With the arrival of summer and all the festivities on the island, she feels lonely and left out. If only she had a boyfriend to waste her afternoons with…
Shawn Newman used to be exactly that boyfriend. Sure, they were together in high school eighteen years ago, and he’s only going to be on his hometown island for a few weeks anyway. He just needs to get the Heartwoods to sell their land…and maybe he needs to kiss Lissa under the bright South Carolina moon.
But the Heartwoods aren’t interested in selling, and Alissa is resistant to his reappearance in her life. As Shawn rediscovers the beauty of the island where he grew up, Lissa confesses that she isn’t looking for long-term, and he agrees to a few weeks of “fun.” Nothing serious.
As they spend more time together, Alissa thinks she might have made a mistake… Can Shawn and Alissa take their relationship out of the fun zone and into something more serious?
