Finn O'Leary has spent God knows how many years trying to drown out his past. Juvenile detention. Bad decisions. Worse choices. He's managed to turn it around - MIT, Dean's List, a sexier-than-thou body with a smile to match - at least on the surface. When his mom asks him to spend the summer with her, Tokyo seems as good a place as any to float through the summer.
Rule #3: Swim at your own risk.
