She's a head-in-the-clouds romance author. As their relationship grows, they meet in places around the world, while continuing to live in different countries. Though their feelings for each other deepen, their priorities remain the same. Simon is in a hurry to be financially sound and settle down, but Tessa is enjoying her freedom and newfound success. Neither is willing to give in, but as each goodbye gets harder, Tessa begins to wonder whether fame is the path to happiness, or if she has everything she needs in Simon. Just as Tessa finds the courage to go after her own happily ever after, the unthinkable happens, separating them in ways she never imagined. To move forward, she must let go of the past and determine once and for all if love is truly more powerful than the pain of goodbye.
