Observe the subject. Analyze the data. Find the rules. Act accordingly. That’s how everything should work—at least, that’s what our science-minded protagonist believed. Until he met her. She’s all feelings, literature, and unpredictability. He’s pure logic and spreadsheets. What happens when a hardcore science guy ends up with a free-spirited liberal arts girl? A hilariously honest (and slightly chaotic) love story—based on the author’s real-life experiences!
