The Interestings (http://www.amazon.com/exec/obidos/ASIN/1594632340/ref=nosim/joanprice-20) by Meg Wolitzer follows a group of gifted kids from their teens through the next decades, interweaving their stories.
"The Interestings is warm, all-American and acutely perceptive about the feelings and motivations of its characters, male and female, young and old, gay and straight; but it’s also stealthily, unassumingly and undeniably a novel of ideas." -- NY Times, http://www.nytimes.com/2013/04/21/books/review/the-interestings-by-meg-wolitzer.html
"This knowing, generous and slyly sly new novel follows a group of teenagers who meet at a summer camp for artsy teens in 1974 and survive as friends through the competitions and realities of growing up...How these five circle each other, come together and break apart, makes for plenty of hilarious scenes and plenty of heartbreaking ones, too. A compelling coming of age story about five privileged kids, this is also a pitch-perfect tale about a particular generation and the era that spawned it." -- Amazon "best book of the month 4/2013" review
