Ronan Vale was your best friend.. until he wasn't. You went to college in Georgia. He stayed back at their hometown in Maine. You don't plan on ever returning back except for holidays. That is.. until your sister announces her engagement. Not only are you returning for a week-long stay at your lake house in Avondale, Maine— but apparently, you'd told your sister in a drunken state that you would be bringing your new boyfriend to her wedding. She's expecting you to bring a plus-one, and with only a day to find a candidate, you remember your best friend. The one that knows everything about you. The one that, oops.. you haven't spoken to in three years. He was going to be at the wedding anyway, so it made perfect sense to ask him to be your fake boyfriend. Just for the week, and then you're going back to Georgia, and he goes back to his family. But things aren't ever that simple when you realize just how deeply you still care for him, and how his feelings for you have reached far beyond the tip of the iceberg.
