Modern Lovers by Emma Straub
From the author of The Vacationers comes another made-for-Summer read, Modern Lovers. College friends and former bandmates Elizabeth, Andrew, and Zoe all live in the same gentrified Brooklyn neighborhood where they have bought houses, opened businesses, and started families. Now, with their own kids getting ready to go to college, they must confront truths about themselves, their kids, and the famous fourth band member who went on to massive fame without them. A smart, thoughtful novel about growing up and getting older.
