Maine is an internet sensation, with an audience of millions reading all her blog updates, listening to every music cover. She's incredibly talented, incredibly famous, and incredibly anonymous. All anyone really knows about her is that she has a killer voice and a penchant for superhero movies.
Enter South: a music-loving, Cosmic Brownie obsessed guy living alone in a Manhattan apartment. Despite living next to him for the better part of two years, Maine's never met him. That is, until she gets locked out of her own apartment.
Now, Maine and South are hardly apart, resulting in a series of possibly unfortunate events, serious bickering over South's beloved Little Debbie treats, and a million and one near-heart attacks for Maine, who is desperate to keep her alter-ego and dreaded past a secret.
