I've been working on Wild Card Undercover for a while and one of the first things I do when I create a new story is to find pictures to inspire me. I put these all on Pinterest in their own story board. Here is how I picture the main characters, Meg O'Hara and Christopher Shaunessy. I've added a little Miami background to set the mood as that's where the story takes place.
Check out my Pinterest board for my inspiration for this story and others.
