“Grant Ginder has written The Big Chill of our times… and possibly done an even better job. So Old, So Young is a triumph. I will never forget these characters.” —Elin Hilderbrand ,

“So Old, So Young is a story of romantic love, professional jealousy, misplaced longing, and—above all—the gift of lifelong friendship.

You will laugh on every page, except for when you find yourself moved to tears.” —Jenny Jackson, New York Times bestselling author of Pineapple Street Six Friends. Five Parties. Twenty Years… How did we get So Old, So Young?From Grant Ginder, the bestselling author of The People We Hate at the Wedding, comes a generation-defining novel that is part love story, part tragic comedy.

Five parties over the course of twenty years bring six college friends together, exploring the ways we run from and cling to our friends in love, life, and death. For Marco and Mia, Sasha and Theo, Richie and Adam, the one constant in life after college together has been change. New jobs.

New cities. New spouses. New children.

Through it all, one thing they thought would always stay the same is their friendship. But time has a way of breaking even the strongest bonds, and testing what we thought we knew. From East Village apartment parties and disastrous destination weddings, to fortieth birthdays and suburban backyard barbecues, Grant Ginder’s resonant, funny, and deeply moving novel is a story about the growing pains of the Millennial generation, and a celebration of how love can shift, stumble, and grow into something bigger than we ever could have imagined.
