Enchanted, Inc. is written by Shanna Swendson and is about Katie Chandler, a woman living in New York. In this book, magic is going on all around us (as I have long suspected) but most of us are completely fooled by it. Katie, however, has absolutely no magic and so can see what is really happening (frog princes, talking gargoyles, etc.)
She ends up teaming up with a magic business. Highjinks ensue, plus a crush.
Okay, it's not War and Peace, but it's a lot of fun.
