Zen and Xander are sisters—truly, madly, deeply sisters, and this is their last summer together. Zen is the "good" girl with a black belt in karate and a newfound penchant for kicking heads. Xander is a wild scientific genius with a self-destructive streak a light-year long. They have three things in common: they’re brown-eyed blondes, they’ve noticed the boy next door has turned into a hottie, and they miss their mom, who died almost a year ago.   These sisters are surviving just fine—except Zen keeps getting into fights that are harder and harder to finish, while Xander spirals into a vortex of late-night parties, scary men, and drugs. What’s worse, Xander has scholarships to the most coveted universities in the country, but she’s about to ruin everything.
