Each of them has big plans with their respective friends for the summer - until they discover that their parents decided to swap houses! Luckily there's no amount of homesickness that a bit of snooping can't cure. Charlie and Molly begin crawling under beds and poking around in closets to find out a little more about each other - and they like what they find. Can Charlie and Molly's long-distance romance survive jealousy, misunderstandings - and the thousand miles between them? MTV's Room Raiders meets You've Got Mail in this sweet, old-fashioned love story for the digital age. . . .
