Erin Oscar is tired of being cheated on---four times in a row is four times too many. She wants the rest of her college experience to be full of passion and fun, and empty of heartbreak and insecurity. But when she meets two boys who, despite being so different, are exactly what she's dreamed of, she realizes she may have bitten off more than she can chew. Taylor Wilk and Riley Broaden are best friends who meet Erin separately, instantly becoming enamored by her, despite her obvious disinterest in choosing one of them to entertain. They've shared everything but girls with each other, but Erin is different, and she's teaching them more and more about themselves and each other than they ever could have imagined.
