Retrograde: Forget Me Not - Elite Series

Nicco and Karissa Carisi are the perfect couple with an ideal life, or so it seemed. One tragic event changes everything and rips them apart. They have both moved on. However, Nicco has unfinished business and Karissa holds the key. Does she want to unlock the door for Nicco? Karissa is presented with two choices; she can be held hostage by their past or she can accept the present and build a future with Nicco.
Nicco has only one choice, right a wrong and regain the only thing that truly matters. Will he be able to convince Karissa that he has learned from the past? Side note, I am Canadian, and the story's location is in Canada. So, the spelling and word usage contained in the story are also Canadian.
