Tessa Waterford is the main character in the first book. She’s 28 years old, and has not had the easiest life. She’s at a point in her life where she’s ‘stuck’, unable to move forward until the day she sees a help-wanted ad that will change her life, and eventually, impact the world because of where it leads her.
She likely has ADHD, deals with intermittent depression, and tends to do the right thing, even when it comes back to bite her. She’s fiercely independent, intelligent, and creative.
