Everyone has wondered "what if?" But how many get a chance to live it?

Seventeen years ago, Olivia Watson's world was turned upside down when she discovered Justin, her high-school sweetheart turned fiancé, having sex with her best friend, Petal. Unable to muster up any forgiveness, she turns her back on him and every friend connected to that part of her life, leaving many questions about the details of the betrayal unanswered.

When Olivia receives an invitation for her twenty-year high school reunion, she decides that she's been avoiding the past for too long. It's time to go back and revisit that part of her life, her old friends, and the betrayal that created the wedge between them.

As soon as she and Justin lay eyes on each other at the reunion, they immediately sense the vibrant remains of their unbreakable connection. The spark between them never faded. However, Justin is now married to Petal and Olivia is involved with Adam, her handsome, best-selling-author boyfriend. But is healing old wounds enough for Olivia and Justin to move forward together, or will it help them make peace with the new lives they have chosen?

Each of the four main characters remain bound to their past by unresolved issues, demonstrating that sometimes we can't find our future until we settle our past. But, most importantly, Olivia learns that forever isn't time eternal; rather, forever is a place we share with the people we love the most - even when they're gone.
