Social media strategist Lauren Wallace plans everything. But when she returns to the charming-if not too small for comfort-town of Seaside Cove, it's only about a second before her tough-love Grams is already on her case. So when Grams tells her not to go to that bar, Lauren decides it's time for a temporary rebellion. Which is exactly when the trouble starts.

Grams was right. The bar was not a good plan. Because suddenly super-cute bar owner Ethan McAllister has gone from being Lauren's (kind of) high school nemesis to a very unexpected one-night stand. And worse, Lauren's attempts to resume her ultra-responsible life keep getting thwarted by more unwelcome spontaneity. And a pregnancy.

Now there's a baby on the way, Lauren's the talk of the entire town, and all her planning has gone right out the window. All that's missing is childbirth to make her pain complete. But it'll be nothing compared to Grams's reaction when she finds out that Lauren broke the biggest rule of all...falling for the wrong guy.
