Nineteen-year-old Lucas Burke prefers being alone. He likes the silence, and he loves not having to care about anyone else's problems: the less he's forced to feel, the better. But after a year of college-induced isolation from everyone he used to know, the wedding of a former classmate sends Lucas back home, and that means reconciling with a group of friends that now might as well be strangers.His sister hardly knows him, his "genius" best friend is nothing more than an addict, and his ex-boyfriend is still in a coma. All the while, wedding preparations send Lucas head first into a relationship with the groom's best man—a recently cancer-free ex-Olympian who can't stop talking.Lucas knows that if he wants to survive the summer, he'll have to learn to be a friend again, but it doesn't come easy, and it might already be too late.
