Ever since readers first met him in Liar, Liar, Kevin's been dying to ask out Tina Zabinski, the Most Beautiful Girl in the World. But since he can barely get a word out when he's around her, it's been hard. And it becomes even more difficult when the school's hunky new guy zeroes in on Tina.Then Kevin gets another one of his brilliant ideas: he's going to take a scientific approach to figuring out how love works…and then he'll ask Tina out. After all, love is based on chemistry and chemistry is science, right? But whether he's setting up a disastrous romantic dinner for his parents or accidentally asking out the wrong girl, Kevin's schemes never seem to go quite as planned.
