Birdie Horne is the combined pen name of former enemies Eden Robins and MW Garguilo. Over the years, they have been love rivals, co-godmothers, and neighbors across an alley in Chicago. Separately, they have published over twenty books, and together they have a resume full of the kinds of jobs that genuinely worry their parents. DON'T CROSS MO ELLERY is their first outing as Birdie Horne.
