Based on the wildly popular Twitter feed Dear Girls Above Me, a roman a clef about how thinking like a couple of girls turned one single guy into a better man.

When Charlie McDowell began sharing his open letters to his noisy upstairs neighbors - two impossibly ditzy female roommates in their mid-twenties - on Twitter, his feed quickly went viral. His followers multiplied and he got the attention of everyone from celebrities to production studios to major media outlets such as Time and Glamour.

Now Dear Girls breaks out of the 140-character limit as Charlie imagines what would happen if he put the wisdom of the girls to the test.

After being unceremoniously dumped by the girl he was certain was "the one," Charlie realized his neighbors' conversations were not only amusing, but also offered him access to a completely uncensored woman's perspective on the world. From the importance of effectively Facebook-stalking potential girlfriends and effortlessly pulling off pastel, to learning when in the early stages of dating is too presumptuous to bring a condom and how to turn food poisoning into a dieting advantage, the girls get Charlie into trouble, but they also get him out of it - without ever having a clue of their impact on him.
