People change, right? John Geitan understood this concept so well because he knew he changed as much as his first love, seven years life-partner, and beloved fiancée, Rue. But when the latter had a completely altered personality, he was more than baffled. After a surgery that removed the tumor in her brain, Rue became an extremely different person--far from who she was and far from whom John met and loved: from a loving daughter to an indifferent child, from someone who couldn't carry a tune to suddenly becoming musically-inclined, and so many other things that completely turned around Rue's personality. These were not just little, subtle, nuanced things; these were major parts of her as a human being. Motivated to bring her back to her old self, John goes beyond measure to unearth the beauty and the dangers of the human mind. John dismantles the hidden nature of human psychology, while ultimately trying to answer some of his most cryptic questions: How deep does love go? How far will he go to save his relationship? Will love still endure should Rue not come back to her old self? Rue tells a story of a man's perseverance to bring back his lost love against all odds-romance, psychology, and mystery, intertwined in a beautifully crafted novel. After all, what can't you do for love?
